Just checking, am I correct that this board cannot be configured to be controlled via UART but requires RC inputs? Reason I am asking is that I use a microcontroller as actual control unit. No problem with creating the PWM Signals required for RC operations but with the serial protocol I would be more flexible, e.g. turn off the motors, read the battery voltage.
If the controller would support USB OTG I could simply hook up there but this is not possible and USB is much harder to code than a simple UART input/output.

I was kind of hoping that I can remap the e.g. FC Pan as TX pin and FC Roll as RX pin or so.

Thanks in advance
