Firmware update and settings
The FETtec AIO 35A – N works with KISS/FETtec FC firmware version 1.3RC47i or
later !The FC and ESC of the FETtec AIO 35A – N board are flashable over the
FETtec Configurator.
Download the FETtec Configurator here:
https://github.com/FETtec/Firmware/releases.
FC Firmware update
choose USB and select the correct COM Port and press connect. You should see
the FETtec FC G4 as shown. Click “Remote Firmware” button and select the
latest available firmware.Press “Flash selected!” FC is flashed now! Settings
can be made in the KISS GUI.
