Note: When using both a receiver and an Air Unit (including a direct connection using a ribbon cable) on the F405 V3 flight controller, there is an issue. This arises because the built-in SBUS receiver on the Air Unit and the external receiver are both connected to the Rx2 pad（SBUS pad） on the flight controller. As a result, the external receiver cannot be recognized properly by the flight controller. To resolve this, it is necessary to disconnect the SBUS wire from the Air Unit or connect the external receiver to the Rx3 pad on the UART3 port.

It is known that SBUS receivers and part of the ELRS receivers conflict with the built-in receiver on the Air Unit in the F405 V3 flight controller.Even ELRS reciver has this issue, but TBS reciver will not affected by this issue.
