Thanks. Divider on the Invertor we will remove.johu wrote: ↑Tue Jul 05, 2022 3:07 pm Now I see the problem. v3 Boards have a 5->3.3V divider on board on the current sensor input. So your 1.65V is divided again, therefor hicurofs
With the voltage you'd have to check the analog signal that goes into the V3 brainboard and how it behaves as you change HV
What fuses do I need to set on attiny13? No output from AtTiny, I think it's because we didn't set fuses.
