I finally managed to get IBUS working on my Eachine 250 Racer (ER250) and here's how! IBUS is digital communication protocol of FlySky/Turnigy controllers. I'm using FlySky FS-i6 with FS-iA6B receiver, but I guess you can use this guide also for SBUS and others. Connecting to CC3D First, you need to use different connector. If you are currently using PWM or PPM on your receiver, you probably use 8 pin connector. For IBUS you need 4 pin FLEX or MAIN connector. Note: I don't use default ER250 position of CC3D, i rotated it -90°so I can access USB from the side. With ER250 you'll get the all needed cables. I already switched the connector on the receiver side so instead of 4 separate cables I have only 2 (blue is not connected). I'm using MAIN port, as FLEX port is on the side of battery tray in my settup. Black is GND, Red +5V, Yellow RX, Blue TX (not connected) CleanFlight setup Note : On older versions of CF/BF there is no
quadcopters, programming, etc.
