The geiger counter board can be powered with +5V power pin of the Flipper Zero

Output pin for measure on arduino cannot be used on the Flipper Zero because output voltage is too low. You can use jack out port instead. This port must be connected on A7 GPIO.

Assuming the toolchain is already installed, copy flipper_geiger directory to applications_user

Plug your Flipper Zero and build the geiger counter :

./fbt launch_app APPSRC=applications_user/flipper_geiger

The program will automatically be launched after compilation
