The Dronetag BS enriches the Dronetag Remote ID device family with an affordable, lightweight and cost-effective solution for all aeromodelers, FPV pilots, and hobbyists. With its affordable price point and lightweight design, the Dronetag BS is a perfect fit for those seeking to comply with FAA (US) and EASA (EU) Remote ID regulations. It is compatible with Remote ID rules in other territories that accept ASTM F3411 or EN 4709-002 standards.
The ready-to-install design of the Dronetag BS ensures a hassle-free setup process. It can be powered using an up to 17V power input or, if preferred, an external LiPo battery can be utilized as an alternative.
Weighing in at only 0.105 oz (1.5 grams) with basic wire antennas and measuring 0.71 x 0.55 x 0.19 in (18 x 14 x 5 mm) in size, the Dronetag BS is suitable even for the smallest aircraft that are required to have Remote ID capabilities. Mounting the BS model is effortless and can be done using double-sided tape or velcro, offering flexibility across multiple aircraft.
Utilizing Bluetooth technology for Remote ID, the Dronetag BS can transmit signals within a range of up to 1.86 miles (3 kilometers) in ideal conditions.
You can manage the BS with ease through our Dronetag App for Android and iOS. No more hassle of disassembling your aircraft just to adjust settings or update the firmware. With our convenient multiplatform mobile app, you can care for everything effortlessly.

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.
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.
Dronetag BS comes in two variants you can see below:

The Dronetag BS Combo is a package with enclosure, battery, charger and antennas turning BS into a completely standalone battery-powered module.

Added support for an active GNSS antenna
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.
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.
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.
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.
This feature is currently in development and a firmware update will be released in the near future.
This feature is currently in development and a firmware update will be released in the near future.
Dronetag BS can feed GPS data to the Betaflight flight control software through the XBUS protocol, acting as a GPS module. Connecting Dronetag BS to the Spektrum telemetry receiver will enable you to access live positioning data.

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.

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.
Never use input voltage that falls outside the operating range of 3.3V to 17V or you damage your device and void the warranty.
We highly advise reviewing the Power Source Installation page.

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.

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.
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)
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.
You should hear a click when the antennas are securely attached.
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.
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.
1. Antenna Installation
Based on the type of antennas you plan to install, there are two ways to put the device into the enclosure. Please identify whether you plan to use the device with wire antennas (follow 1.1) or another type of antennas (follow 1.2) and proceed accordingly below. For U.FL connector handling, please get familiar with this guide before you start the installation.
1.1. BS with Wire Antennas Attach the wire antennas to the BS unit following the provided instructions. Ensure a secure attachment by listening for a click sound.
Slide the BS unit with the installed wire antennas into the enclosure. Guide the wire antennas through the designated holes in the enclosure, allowing them to extend outside. Ensure that the BS unit is securely positioned within the enclosure and correctly inserted into the designated socket.
1.2. Other Antennas Installation
Wire the disconnected U.FL antenna connectors through the enclosure. Attach the antennas to the BS unit as instructed and confirm a secure connection by listening for the click sound.
Slide the BS unit with the installed antennas into the enclosure. Guide the wire antennas through the designated holes in the enclosure, allowing them to extend outside.
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.

Before you start updating the firmware and during the process, please be sure to:
Not following the guidelines above may lead to bricking the device.
The Bluetooth update is a fast and easy option to update your BS firmware to the latest version. To update the firmware, our Dronetag mobile application must be used.
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.
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.
The connector placed on the left side of the Dronetag BS is a common JST SH 4-pin with UART interface with no flow control. This connector will also be used for support for Betaflight communication and Spektrum Telemetry XBUS in the future.

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.
When an external battery is used, the Dronetag BS unit achieves full standalone functionality.
For your convenience, we offer the BS as a Combo, making the BS the smallest and lightest Remote ID standalone module on the market.
The BS Combo contains a LiPo battery capable of powering the Dronetag BS unit for over 3 hours, packed together with a designed 3D printed enclosure and a separate USB-C 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.
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.
Please watch out for these potential issues when looking for a suitable location and the type of attachment of the BS:

The Remote ID system enables drones to broadcast their location and identification details, which can be picked up by various participants in the airspace, such as pilots, authorities, and even the general public.
The Direct/Broadcast Remote ID refers to the use of Wi-Fi or Bluetooth technology to transmit Remote ID information to nearby areas. The nomenclature for this method differs depending on the location: in the EU, it is called Direct Remote ID, while in the US, it is referred to as Broadcast Remote ID.
ASD-STAN EN 4709-002 is a European standard that provides guidelines for the development and implementation of Remote ID (identification) for unmanned aircraft systems (UAS), also known as drones. The standard specifies the technical requirements and performance criteria for Remote ID systems, which are used to identify and locate drones in flight. This information is transmitted to other airspace users, including authorities, pilots, and the general public. The goal of this standard is to improve the safety and security of drone operations and promote the integration of drones into the existing airspace system.
ASTM F3411-22 is a standard developed by the American Society for Testing and Materials (ASTM) that provides technical requirements for the design and performance of Remote ID (identification) systems for unmanned aircraft systems (UAS), also known as drones. The standard specifies the characteristics of the Remote ID message and the communication protocols that should be used for broadcasting the message. ASTM F3411-22 is intended to support the safe integration of drones into the national airspace system by enabling remote identification of UAS operations. The standard provides a consistent and interoperable framework for Remote ID systems to ensure that the information can be received and interpreted by other airspace participants, including authorities, pilots, and the general public. This standard is regularly reviewed and updated to keep pace with technological advancements and changing industry needs.
