This board supports most serial external receivers via UART3. Officially supporting FrSky XM and XM+ (SBUS), LemonRX DSM2 and DSMX (SBUS), and FlySky FS-A8S (iBUS) satellites.

F4 doesn't have builtin inverter and the Alienwhoop F4 V2 board doesn't have it either. So we need to modify the receiver. Know more about the inverted signal on STMF4 in Oscarliang's blog.

Here is the connection diagram of Frsky XM and Alienwhoop F4 V2 board.
