Topic: Read self voltage using ATSAMD21G18A board (Read 569 times) previous topic - next topic


I'm trying to make a minimalist gsm phone using ATSAMD21G18A micrcontroller (arduino zero bootloader). I need to measure the battery voltage to display on the lcd. I found THIS link for arduino uno and similar boards but it doesn't support arduino zero.

is there any similar functionality available for arduino zero?
