Warning

Who is it for?​

Dronetag BS is mainly for skilled recreational pilots (RC modelers, FPV pilots, hobbyists) seeking the simplest and most flexible Remote ID solution on the market to comply with the latest regulations. It is unsuitable for people looking for a plug & play solution as it requires at least some basic electronic expertise to have it up and running. The customers need to find an appropriate power source on their aircraft and do the setup + wiring themselves. If you are looking for off-the-shelf solutions, please get Dronetag Beacon or Mini.

Customers using off-the-shelf drones such as DJI are most likely unable to use BS due to the lack of open interfaces/power outputs available on such aircraft.

Difference between Dronetag BS and Dronetag DRI​

The main difference between BS and DRI is the ability to work as a standalone system. Dronetag BS has everything needed to get you Remote ID compliant, which includes an internal GNSS receiver. On the other hand, Dronetag DRI is mainly an OEM product for integrators and manufacturers that relies on sensor information being provided by the flight controller. If you need a self-contained & standalone system, go with Dronetag BS. If you need Standard Remote ID implementation, it is suggested to go with Dronetag DRI.

High-level List of Features

Flexible Antenna Selection​

Dronetag BS comes with two standard U.FL connectors for external GNSS positioning and Bluetooth broadcasting antennas. This gives customers the freedom to select the specific antenna shape, size, cable length and performance. The only requirement we put on the antenna selection is that they must be U.FL compatible and the Bluetooth antenna must be tuned for 2.4 GHz and the GNSS antenna for 1.575 GHz.

Flexible Power Input Source​

Dronetag BS can be powered from any power input capable of supplying 3.3V to 17V. It uses a buck regulator to convert the power input to an internal voltage level. The power source must withstand 50 mA peak currents at 3.3V. The most common place to get power input is the regulated voltage on the flight controller, or you can use an aircraft battery (up to 4S Li-Po). For some scenarios, you can also use a small external single-cell LiPo battery to power the device.

GNSS Input to Betaflight​

If you use a Betaflight controller, you can use Dronetag BS as a GNSS input for telemetry information and the GPS rescue feature. The device uses the ublox M10 chipset, which provides state-of-the-art positioning for your aircraft.

GNSS Timekeeping with Supercapacitor​

Waiting for a GNSS fix can be a lengthy process. And it isn't very pleasant when you already had the fix, but you power-cycled your aircraft, and you have to wait for the GNSS fix again. For this reason, we added a tiny supercapacitor to the board, which can hold up the GNSS data in RAM for around 8 minutes. This means that whenever you have a position fix and you do a power cycle of the BS, you won't have to wait again to acquire a fix as the data will be stored inside the RAM. This feature dramatically reduces the time to first fix (TTFF) so you can experience continuous flying during the battery change process.

Operating as Telemetry Modules for Futaba, Spektrum, etc.​

This feature is currently in development and a firmware update will be released in the near future.

Flight Data Logging into Internal Flash Memory​

This feature is currently in development and a firmware update will be released in the near future.

Integration with Spektrum devices

New Feature Introduced in the Latest Firmware Update​

The Dronetag BS now supports integration with Spektrum receivers. By connecting the Dronetag BS to an SRXL2-compatible or XBUS-compatible device, the BS supplies additional telemetry data that is seamlessly transmitted to your drone's transmitter. This allows you to view important telemetry information directly on your transmitter display during operation, enhancing your situational awareness and providing additional data you may require for safe and efficient drone flights.

SRXL2 Setup and Connection Manual​

1. Setup​

In this example, we’ll use the Spektrum receiver AR6610T, which provides SRXL2 as well as an XBUS interface.

2. Connection​

To connect the SRXL2-compatible device to the Dronetag BS, you’ll need to make a custom cable. On the Dronetag BS side, the cable requires a 3-pin connector (3-pin JST SH Series). On the Spektrum side, refer to the appropriate connector specified in the device datasheet (in our case, a 4-pin JST ZH connector with a 1.5 mm pitch - one pin is unused).

Keep in mind that the Dronetag BS still requires power. Ensure the power pins are connected, and verify that the Spektrum device can supply sufficient current. Refer to the image below for guidance:

For the pinout reference:

  • BS side: Refer to the 3-pin connector description.
  • Spektrum side: Refer to the device's datasheet.

3. Power On and Operation​

  • No special power-up sequence is required.
  • No additional settings need to be configured in the Dronetag mobile app.

After powering on both devices, you should see the live telemetry data on the screen of the transmitter (in this example Spektrum NX6 DSMX) as soon as the Dronetag BS obtains a GPS fix.

XBUS Setup and Connection Manual​

1. Setup​

For this XBUS example, we’ll use the Spektrum receiver AR6610T.

2. Connection​

To connect an XBUS-compatible device to the Dronetag BS, you’ll need to create a custom cable, slightly different from the SRXL2 configuration. On the Dronetag BS side, the cable requires a 4-pin connector (4-pin JST SH Series). On the Spektrum side, refer to the appropriate connector specified in the device datasheet (in this case, a 4-pin JST ZH connector with a 1.5 mm pitch).

Keep in mind that the Dronetag BS still requires power. Ensure the power pins are connected, and confirm that the Spektrum device can supply sufficient current. Refer to the image below for guidance.

Pinout reference:

  • BS side: Refer to the 4-pin connector description below.
  • Spektrum side: Refer to the device's datasheet.

3. Power On and Operation​

There are specific steps required to establish communication with XBUS:

  • Configuration settings:
    Open the Dronetag app, navigate to the "Configuration" section, and under "4 Pin Connector Selection," set the function to "Spektrum XBUS."

  • Power-up sequence:
    Both devices must be powered on simultaneously to ensure the initial XBUS handshake is established. If powered on separately, the handshake may fail, and communication will not work.

After a successful connection, you should see the telemetry information displayed on the screen of your transmitter.

Usage Options

Whether you have a drone that you built yourself, you fly an FPV drone, or you have any kind of aircraft, with Dronetag BS you can rest assured that you will find a solution that perfectly aligns with your unique needs.

The beauty of BS lies in its design and multi-scalability, which enables effortless customization. We understand that no two customers are the same, and that's why we have meticulously crafted BS with components, ready to meet any specific requirement.

Enclosure Options​

Warning
  • Never use the device without either a heat shrink tube or an enclosure! Otherwise you damage your device and void the warranty. The exposed board is sensitive to accidental tearing off of electronic parts, which will prevent the device from normal operation. It is also prone to a short circuit, which might cause a fire on your aircraft.

Heat-Shrink Tube

When used with our basic wire antennas and external power source, the heat shrink tube option is the lightest option available (1.5 grams in total). Please check out this page on how to install the heat shrink tube.


Enclosure

For extra protection and easier transferability between different aircraft models, we recommend purchasing the optional 3D printed enclosure. Compared to the heat shrink tube option, the weight increases by 1.5 grams (3 grams in total). Please check out this page on how to install the enclosure.


Power Input Options​

Warning

External Power Supply

You can power Dronetag BS directly from your aircraft if you have suitable power output ports available. Please check the section Powering from Aircraft VIN for more details. Using the power from the aircraft eliminates the need to use an external battery.


External Battery

By incorporating an external battery, Dronetag BS becomes a completely standalone unit. However, you need to think of the battery placement as the current enclosure or heat shrink tube doesn't allow the battery to be fitted in. Therefore, your own enclosure, heat shrink tube or mounting needs to be established. You can get our small LiPo battery that can power up Dronetag BS for more than 4 hours.


Antenna Options:​

Wire Antennas

Wire antennas are part of the minimalistic approach of Dronetag BS product. They are very compact and lightweight (just 0.15 grams each). However, their performance might be very limiting in some scenarios (e.g. big electromagnetic interference due to high transmission power of other aircraft onboard equipment). Please ensure to upload assisted GNSS data before each flight (the upload can be done via our Dronetag app, check the short video here). This step is needed due to the limited power of the Wire antennas.


Copper Tube antennas

For better positioning and broadcasting performance, we recommend getting a pair of our copper tube antennas (GNSS and Bluetooth). They provide higher flexibility when you want to place Dronetag BS into the fuselage because then you can easily wire the antennas out of the aircraft.


Custom Antennas

If the two above options don't suit your needs, you can also use 3rd party options available on the market. However, you must ensure that the Bluetooth antenna for Remote ID is tuned for 2.4 GHz and the GNSS antenna for positioning is tuned for 1.575 GHz. One of the popular 3rd party options is combined Bluetooth and GNSS antenna that comes with an adhesive.


Caution
  • Never use Dronetag BS without antennas or you damage your device and void the warranty. Always stick to the antenna options above. If you are unsure about the antenna selection, ask us for a recommendation / approval.

Heat-shrink Tube Installation

Items Required​

  1. Dronetag BS unit
  2. Heat-shrink tube
  3. Selected antennas
  4. Heat gun
warning
  • It's important to use a heat gun designed for this purpose, as uncontrolled heat sources can result in uneven shrinkage, physical damage, and insulation failure.
  • Only use a heatgun to shrink the tube around the BS unit. Avoid using an open flame as a substitute for a heat gun, as this can lead to damage and safety hazards.
  • Follow these instructions carefully to ensure a successful heat shrink tube installation. Any deviations may result in improper insulation, damage to the equipment, or safety hazards. Always prioritize safety when using heat tools and ensure proper ventilation while operating the heat gun.

Procedure​

1. U.FL Antenna Installation

U.FL connectors are commonly used for antenna connections in space constrained products such as our Dronetag DRI and Dronetag BS. Due to their size, they are not designed with regular reconnection in mind, and they are only rated for a few dozen mating cycles (usually just 30). It is therefore crucial to select the proper antenna and ideally connect it once for the lifetime of the product. However, U.FL connectors are suitable for scenarios where you need to do the antenna replacement (e.g. when it is no longer working properly or you upgrade to a better antenna).

Before you try to connect or disconnect the U.FL antennas on our products, we recommend studying the U.FL tips from SparkFun and reading the instructions below.

U.FL connector mating and unmating process (source Seeed Studio)

How to Connect U.FL​

  1. Disconnect your device from any power supply and keep it turned off.
  2. Take the U.FL antenna and align it accurately over the U.FL female counterpart on the PCB board.
  3. Press down gently until you hear a satisfying click.
  4. Check whether you can rotate the antenna freely and if possible, protect the connector from external factors.
Caution
  • If it takes too much force for the connection, you are probably misaligned.

How to Disconnect U.FL​

Disconnecting the U.FL can be quite tricky as there is a possibility of damaging the PCB board counterpart or antenna. Be careful during the process. You shouldn't need any tool for the removal and we strongly discourage using a screwdriver or similar that might damage the PCB board.

  1. Hold the cable with your nails as close to the connector as possible (ideally try to hold the metal stiffener built into the connector)
  2. Gently rotate and tilt the cable from the connector all the way up until it pulls away.
  3. Inspect the connectors on both sides and examine them for possible damage.
Caution
  • For the removal process, you shouldn't really need much force to do it.

You should hear a click when the antennas are securely attached.

Caution
  • Ensure that you orient the antennas correctly, ensuring that the GNSS antenna and the Bluetooth antenna align with the appropriate connectors on the BS unit.
  • If you are using wire antennas, the shorter one with black isolation is for Bluetooth Remote ID and the longer one with gray isolation is for GNSS positioning.

2. Insertion into Heat Shrink Tube Carefully slide the BS unit with the installed antennas into the heat-shrink tube. Position the BS unit in the center of the tube. Make sure the antennas protrude from one end of the tube, while the battery connectors are accessible from the other end. Heat-shrink tube must be positioned evenly around the BS unit.

3. Even Application of Heat Begin heating the tube by moving the heat gun back and forth along the length of the tube. This ensures even distribution of heat and prevents damage to the wire inside. Do not concentrate heat in one spot for too long, as this can cause overheating and wire damage.

5. Secure Attachment Continue applying heat until the heat shrink tube tightly conforms to the shape of the BS unit. The tube should be securely attached to the BS unit and covering the U.FL connectors.

6. Cooling Period Allow the assembly to cool down for a moment before handling it. This ensures that the tube is no longer extremely hot and can be safely touched.

7. Final Check Once the tube has cooled down, visually inspect the installation to ensure that the tube is securely attached, antennas are properly positioned, and battery connectors are accessible.

8. Usage After confirming the secure and proper installation of the heat shrink tube, the BS unit with antennas can be used as intended.

Where to Get Heat-shrink Tube Replacement?​

If you for some reason need a new heat-shrink tube for Dronetag BS, please contact your local electronics/hobby store for replacement. You must ensure that the replacement is transparent with a length of 17mm, diameter before shrinkage approx. 12 mm, and diameter after shrinking: approx 7.5 mm.

How to Remove Dronetag BS from the Enclosure

Warning
  • The use of tweezers and a heat gun, if not executed with precision, can lead to severe damage. Tampering with internal components may void your warranty and result in irreparable harm to your device. Ensure the BS is disconnected from the power source before proceeding with any of these steps. Performing these actions while the power source is active may result in injury!
  • Constantly bear in mind that the use of tweezers involves direct contact with printed circuit boards, posing a risk of damage. Additionally, exercise meticulous temperature control when employing a heat gun. Ensure the temperature never surpasses 60 degrees Celsius under any circumstances, and avoid prolonged exposure to hot air. This precautionary measure is crucial to prevent both your device and its packaging from melting during the process.

If you need to remove the BS from the enclosure, such as for antenna replacement, always adhere to the following instructions. There are two methods at your disposal, and for both, you'll require a hair dryer/Heatgun and Tweezers. We strongly advise against using tweezers with a different shape than those with flat and blunt ends, as shown in the image below. The use of differently shaped tweezers may result in damage to the BS itself, voiding the warranty.

Recommended Tweezer

Method 1: Extrusion​

Apply hot air to the enclosure, ensuring the temperature remains below 60 degrees Celsius, for a few seconds. As the package softens, use tweezers to gently push the BS through the hole located beneath the left antenna. A small cutout beneath the left antenna hole, visible when viewing the enclosure with the Dronetag logo on top, can guide you.

Method 2: Extraction​

Delicately heat the package with a hair dryer or heat gun, keeping the temperature below 60 degrees Celsius. As the package softens, use tweezers to extract the BS. Use tweezers to grip the BS between the connectors; avoid holding the BS directly by the connectors to prevent damage.

Power Source Installation

The Dronetag BS unit is designed to operate with power inputs ranging from 3.3V to 17V. It employs a buck regulator mechanism to convert the incoming power to an internal voltage level. It's important to note that the power source chosen should be capable of handling peak currents of up to 50 mA at 3.3V.

The most commonly utilized sources for power input include the regulated voltage output from the flight controller. Alternatively, you have the option to utilize an aircraft battery, with support for up to 4S Li-Po configurations. For minimalistic usage, a compact external single-cell LiPo battery can also serve as a suitable power source for the device.

Important update for products shipped before 10/16/2023

Using powerful batteries to power BS can potentially cause damage. Please read the Notice for products bought before 10/16/2023.

Where to Put Power Source?​

Dronetag BS has two connectors on the front side. Both of these connectors can be used as a power input, however, the use depends on your scenario. We have prepared the right 3-pin connector as a plug & play for our Li-Po battery. The use of the 4-pin connector on the left side for power supply is of course also possible, but it is necessary to follow the Wiring diagram below.

Danger
  • Never supply both connectors with power input or you damage the device and connected power sources.
  • Never use input voltage that falls outside the operating range of 3.3V to 17V or you damage the device and void the warranty.

When choosing this type of power supply, you need to connect the BS with a cable to the power source. Always follow the rule that the power source chosen should be capable of handling peak currents of up to 50 mA at 3.3V.

Powered by External Battery​

When an external battery is used, the Dronetag BS unit achieves full standalone functionality. Nonetheless, it's essential to consider the placement of the battery due to the current enclosure or heat shrink tube design limitations that prevent its accommodation. As a solution, you would need to create your custom enclosure, heat shrink tube, or mounting mechanism for the battery.

For your convenience, we offer a compact LiPo battery capable of powering the Dronetag BS unit for over 4 hours. This battery provides an excellent power source to ensure extended operational durations.

How to Use the Battery Charger​

Operating with an input voltage of 5V, the charger maintains a charging current within the range of 50-200 mA. Adjusting the charging current is achievable through the soldering of specific jumpers on the charger's rear side. Connecting these jumpers together empowers you to enhance the charger's power output. It is imperative to underscore that any modifications in this regard are entirely your responsibility and should align with the specific battery you intend to charge. Please exercise the utmost caution, ensuring compatibility and implementing adequate safety measures during the modification process.

The board is also equipped with integrated circuits that offer protective functions, guarding the battery against overcharge, undercharge, and short circuits. Additionally, the board features a singular LED to indicate the ongoing charging status.

Notice for products bought before 10/16/2023

Dronetag BS is engineered to operate with power sources of up to 17 volts. However, when connecting a 4S battery with a voltage of 16.8 volts, there is a potential for a transient event to occur, overshooting by a factor of more than double voltage, exceeding 30 volts, leading to sparking and damaging the Dronetag BS.

This only affects products that were shipped before 10/16/2023.


Therefore, if you are powering the Dronetag BS directly from the battery, we suggest the following possible precautions:

  1. Choose another way of power supply - e.g. from the balance connector (use only 1S or 2S).

  2. Limit the current voltage by adding a resistor to the power path to the BS (any from 4R7 to 120R will do).

  1. Limit the transient by connecting a rectifier diode to the power path (e.g. 1N400x, 1N4148 will also do).

BS sent after 10/16/2023 will have this problem solved as a new revision of the BS will be introduced.

Attaching to the Drone

The BS can be attached to the drone in multiple ways, depending on your decision regarding the enclosure. Please check the section BS options.

If you use BS without an enclosure, you can attach it using an M2 screw mounting hole or double-sided adhesive tape or velcro.

If you decide to use BS with an enclosure, you can attach it using double-sided adhesive tape or velcro, no M2 holes are possible with the enclosure.

*When using velcro, we advise using a 3M Dual Lock with interlocking mushroom-shaped heads. They slide past each other to close with a snap and peel apart easily when you need to separate them by simply pulling the strips by hand.

Proper Location and attachment advice​

Please watch out for these potential issues when looking for a suitable location and the type of attachment of the BS:

  • If you are using a double-sided tape, please follow the manufacturer's recommendation, as some require some time curing for proper attachment.
  • If mounted by double-sided tape, don't place BS over a curved surface because it might come off during flight.
  • If mounted by double-sided tape, don't place BS on a soft material that can bend during mating (such as plastic covers). The double-sided tape may not hold properly.
  • It is recommended to place BS in accessible locations. You should have the LEDs visible.
  • When using an external antenna please do not choose a location with any metal surfaces and carbon tubing to prevent antenna detuning.
