The DroneBeacon db121 is a so-called direct or broadcast Remote ID long-range transponder, equipped with its own GPS receiver and needs to be powered by the drone. A transponder is also called add-on, tracker, tag or (wireless) number plate. The db121 has two flavors: a transponder with enclosure or a PCB only. It is compliant with the (upcoming) standards in the EU and USA. The FAA has approved the db121/db121pcb for usage in the USA. Furthermore, the transponder is optimized for long range due to its transmit power and antenna design. It also supports all transmission protocols for maximum flexibility.
DroneBeacon db121 can be attached to a drone by using the included M3 dual-lock stickers or use the M5 screw noses. On the other hand the db121pcb has 4x M2 holes. There is a status LED to show the status. The transponder can be configured easy using any device, by pressing the configuration button and connect to the dronebeacon Access Point.
Users (in the USA) need to register their drone at the FAA website: https://www.faa.gov/uas/getting_started/register_drone In the EU you need to enter the operator ID in the configuration settings.
If you need a transponder with battery, the db120 is a better choice. If you want to use an external GPS receiver, the db122fpv will be a better fit.
