FW1A voltage read out is low.

Hi. Is there a voltage Calibration for anduril? I have late model FW1A purchased from Neal’s on black Friday. The voltage read out is 0.1-0.2 volts low. It shows 4.0V on a fully charged cell and continues to be at least 0.1V low when displaying voltage. Can this be adjusted?

Not in currently released versions. Anduril 2 has voltage calibration.

So is it just wrong? Can’t do anything about it?

You could flash a new firmware. Requires complete disassembly, remove the driver, use a SOIC clip and an AVR ISP programmer, flash Anduril 2 (or Anduril 1 with adjusted voltage offset).

Thanks. I’m trying to avoid that much work, especially since I’ve never flashed firmware. But thanks.

Too bad. Not catastrophic though so I’ll live.
