UART stands for Universal Asynchronous Receiver Transmitter.
UARTs are used on Flight Controllers to transfer data between the
flight controller itself and external devices such as a radio receiver.
Each UART port has a receiver (RX) for input and transmitter (TX)
for output. If the flight controller is accepting information, such as in
the case of control link receiver, the RX pad will be used. If the flight
controller is sending information, such as commands to the video
transmitter, the TX pad will be used.
The table below outlines the Riot Control FC’s UARTs and their
recommended uses. Only one function may be assigned to each
UART. For example, if UART1 is used for the receiver, and UART6
is used for VTX control, UART3 can only be used for one of the
follwing functions: ESC telemetry, RunCam Split control, FrSky
S.Port Telemetry.
