DJI FPV Wiring Guide - How to connect to Betaflight

IMPORTANT NOTE: After more long-term testing, I do NOT recommend this flight controller for use with the DJI system because the 9V regulator is not a sufficient power source. While it worked for me on this one board (which is why I used it for this video) many others have reported the DJI system cutting out due to insufficient power. I recommend using the Hobbywing flight controller. The connections shown in this video still apply, just use a FC with a more reliable power supply.
Walking through the different connections for the DJI Digital FPV System.
1:25 - Power & Ground (red & black wires) - powers the system so that it will provide video to the goggles. The system can now be used for FPV
3:15 - MSP connection (white & grey wires) - connects the DJI Air Unit to betaflight which will allow for data communication. Provides for On Screen Display, PID tuning, and other functions in the DJI goggles
5:52 - RX connection (yellow & brown wires) - DJI Air Unit provides reciever signal to Betaflight. SBUS or DJI HDL protocol
