Here’s a wiring diagram for interconnecting a Matek F722-MiniSE to a Runcam Split 4, Matek VTX-Mini, Holybro Tekko32 F3 Mini 4-in1 ESC and FrSky R-XSR. I used this setup in my Hornet 3″ drone build.
Points to note:
- The Matek F722-minise web page has some very helpful information regarding Betaflight configuration and connectivity.
- The image has a Runcam Split S 3 shown – check the RX/TX wiring as the Runcam 4 vs 3 has reversed pins.
