Hi Claus,

i tried to make measuring the battery level to work, but it seems like GPIO 34 is not connected to anything on a stock HiGrow-Board (trying to trace back if this PIN on HiGrow would be able to detect something).
Also i couldn't find any schematics to find out if this PIN is even connected to something.

Could you share your ideas what you wanted to do with GPIO 34?
How could we measure the battery level without adding a seperate chip or having to deal with a drain to ground? E.g. using another PIN in OUTPUT-Mode to turn on a transistor so we could intercept the voltage-divider to prevent the drain?

Cheers,
André
