Hinterbergstrasse 15 FTD-088 CH-6330 Cham Introduction Atom UAV is a FLARM developed specifically for drones. Leveraging the Atom SoC platform, it is a miniature, feature-packed device that can be used standalone (“hook-on”, retrofit) or integrated into own designs. Highlights: Atom System-on-Chip platform ...
Power consumption: 200 mW typical 1.1.2 Description The Atom UAV is equipped with two microcontrollers and thus needs two firmwares to operate. The Atom SoC runs the FLARM radio protocol. The Espressif-based periphery processor runs FLARM Hub and provides connectivity via WiFi, USB and the JST/TFM connector.
JST GH The GH connector from JST is used on the Atom UAV standalone variant over the DF-13 for its improved mechanical properties and ease of handling. It exposes a 3.3 V UART and may be used to supply power. The pinout is identical to what is used in Pixhawk-based flight controllers: 1.1.7...
When connecting to a Pixhawk or similar flight controller, the RX and TX lines must be crossed, i.e. TX of the flight controller must be connected to RX of the Atom UAV, etc. The JST GH receptacle is surface-mounted to the board, thus the mechanical stability is limited.
FTD-088 CH-6330 Cham Interfaces The Atom UAV can provide traffic information on both the USB connector and JST/TFM connector and provides different protocols. Please note that currently the external GNSS source is activated by enabling the EXG license. In order to use the internal GNSS source, the EXG license needs to be disabled.
QGroundControl (verified on v4.1.1) Other GCS may offer support, too. JSON A JSON message stream providing a user friendly to interface with Atom UAV is available on the JST port. A detailed interface description can be found in document FTD-092.
On the navigation bar of the page, go to “Maintenance”, “Firmware Update”. To update the Atom with a new PowerFLARM Firmware, a .fw file is needed. To update FLARM HUB, a .bin file is needed. Port Configuration The protocol and baudrate on the JST port can be configured on the Web Interface...

Enable/ Disable EXG Licence The selection of either an external or internal GNSS source is done through the EXG license.

It can be enabled again by sending “$file,mv,lic-EXG.tmp,lic-EXG.bin”. In the output field, a response should be listed.
CH-6330 Cham Radio diversity Atom UAV can only be connected to one antenna. However, multiple antennas might sometimes be required to ensure sufficient radio coverage. With Atom UAV, it is possible to use two devices to provide this radio diversity. Both devices will emit the same ID (and thus be seens as one aircraft by other receivers) and ignore each other.
