DJI Air Unit Compatibility
Compatible with all DJI Air Units: DJI O3/RunCam Link/Caddx Vista/DJI Air Unit V1. Please
use the solder pads <9V, G, T1, R1, G, SUBS(R2)> on the front right corner of the flight
controller to make a pin-to-pin connection with the solder pads on the DJI Air Unit.
UART1(T1, R1) is used for OSD and SUBS(R2) is used for DJI Air Unit’s internal SBUS
receiver signal input.
