DJI Air Unit Connection Way Direct soldering
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.
