You can also have more than one receiver in the system at a time (usually used for long range hand-offs to a remote TX). See :ref:`common-multiple-rx` for details. + +Any UART can be used for RC system connections in ArduPilot also, and is compatible with all protocols except PPM (SBUS requires external inversion on other UARTs). See :ref:`common-rc-systems` for details. + +OSD Support +=========== + +The BETAFPV F4 1S 12A AIO V3 supports DJI HD air units with telemetry using UART4 RX/TX.
