This package will manage the fan and power buttons in the Argon One case on Raspberry Pi 4 and 5.
Please keep in mind that the Argon One v3 on Pi 5 requires a modded EEPROM, please see the official instructions.
Thanks to Martin Wimpress for his Ubuntu Port and Argon 40 for pretty much everything else.
