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.
1.1.3
RF Connectors
There are three MCX connectors, documented as GNSS, ADSB and FLARM on the
PCB, next to the connectors. The Flarm RF antenna must be pointed vertically
(perpendicular to sea level) in the final installation.
