Special Notes for SBUS Receiver
When using an SBUS receiver, the SBUS signal wire must be connected to the SBUS pad on the front of the FC (which uses Serial 2). If the DJI Air Unit is also connected via the dedicated 6-pin socket on the back of the FC, the SBUS signal wire from the Air Unit's cable must be disconnected from the FC. This can be done by carefully removing the wire from the 6-pin connector or cutting it and insulating the end.
Diagram illustrating the SBUS connection and the warning about disconnecting the DJI Air Unit's SBUS wire.
Special Notes for ELRS Receiver
It is recommended to connect the ELRS receiver's TX and RX to the FC's T2 and R2 pads. If the DJI Air Unit is also used, some ELRS receivers may not be recognized correctly. In such cases, disconnect the SBUS signal wire from the DJI Air Unit's cable from the FC. This can be done by carefully removing the wire from the 6-pin connector or cutting it and insulating the end.

FC and O3 FPV Connection
Use the 6-pin cable included with the O3 FPV Air Unit.

ESC Setup and Firmware Update
The ESCs in the F7 V3 Stack are 32-bit BLHeli32 ESCs. As BLHeli32 is closed-source, Bluetooth parameter tuning is not available in the Speedy Bee app. Please download the latest BLHeliSuite32 ground station software on your computer for ESC configuration: https://github.com/bitdump/BLHeli/releases.
However, the app still supports changing motor direction. Connect to the app, go to the Motor page, and click the option shown to easily change motor direction.
