The Tempest F4 is compatible with Betaflight using the new MLTEMPF4 board target. Cables are included for direct plug-in to an HS1177 camera and a Unify Pro HV VTX.

Note: The VTX will display a screen full of the letter "V" until a font is uploaded. Use the "Upload Font" button on the Configurator VTX tab and select a font. The VTX must be powered from lipo during upload.

Recommended installation is to pre-tin and trim wires, insert them from the bottom side, and solder on the top.
