Replacing ATtiny solved issue, not sure what caused it

mechatroniks-git commented 3 years ago

Replaced with ATtiny1624 (2-Series) chip and programmed with Megatinycore v2.3.1 using this code: https://github.com/tetrabiodistributed/PAPRA-PCB/blob/c38be3ee90f81fe9fc7fcec78938d70674fdf67d/firmware/papracode/papracode.ino. Board is fully functional, will keep testing.

Failure likely caused by GND-SENSE input to microcontroller
