The SynergyF4 was designed as an upgrade to your standard F4 flight controller with a focus on cleaner and easier building. A TBS Unify Pro V3 or a Unify Nano can be directly mounted to the surface of the board with no tape or zipties required. In addition, the FrSky XM+ and TBS Crossfire Nano can be directly mounted to the board for a quick and easy build process.
Solder bridge selectors on the bottom of the board allow for a wide range of components to be used with the FC.
Note: This FC is compatible with any receiver and video transmitter. Simply connect the rx/vtx with wires to the correct pads.

SYNERGYF4 TARGET NOW LIVE WITH BF 3.5.7
Pit mode “mode” selection in the modes tab will be used to control the vtx. The above CLI commands set the mode switch to control the pin output instead of sending a command to the VTX to go to the “graveyard” channel.
Before: Pit Mode - command VTX to go to its assigned graveyard channel via SmartAudio.
After: Pit Mode - controls output of Pin B15 to output a “HIGH” or “LOW” command which controls the power that the VTX receives.
