I have a SparkFun Pro nRF52840 Mini - Bluetooth Development Board that I’d like to read the battery voltage on. I’ve searched forums and the internet and can’t readily find any information on doing so. Would anyone have any pointers? Coding using Arduino.
That board doesn’t have built-in/wired Lipo voltage sensing…some of our boards do (any that say ‘fuel gauge’ do)
You can wire the Lipo to this SparkFun LiPo Fuel Gauge - TOL-20680 - SparkFun Electronics (send power using the +/- to the +/- on the nrf board) and wire it over i2c if you want. Or check out some of the other ones that we carry
Thank you!!!
