I have been looking at pinouts and docs and code and I must admit Im a little confused by the UARTs.
I just ordered a Graupner MX-20 HOTT to use instead of my Spektrum DX8i, in the hope I can use the hott-for-ardupilot modules for integrated telemetry.
I am trying to digest the difference between UART0/2 vs UART0/UART2. Is UART0/2 both UARTS, and UART2 is only available if i do the usb mux solder bridge? Im a little lost.
Ideally I would like to use both 3DR Radio (and OSD)/Standard USB and have another serial connection for the HOTT receiver. Is this even possible?
