Modules Reset to factory default - MobiFlight/MobiFlight-Connector GitHub Wiki
Reset a module
In the case that you wanted to convert your MobiFlight board back to the standard Arduino (or other compatible board), there is a built-in option for that in MobiFlight > Settings > MobiFlight Module (Tab)
The procedure will upload a new sketch which:
- erases your EEPROM once
- behaves like the standard "Blink"-sketch that usually was on your Arduino board when it came from the factory.
