Adafruit ItsyBitsy nRF52840 Express - Bluetooth LE

by PVAR09 on Thu Jan 13, 2022 5:03 pm

I have purchased battery back pack add on (Adafruit LiIon/LiPoly Backpack Add-On for Pro Trinket/ItsyBitsy) and connected a battery to my board.

When i plug it in with the USB, both the red charging light and the green DON light come on.

When i disconnect the USB the battery doesn't power the board.

Whats wrong?

We only support usage with LiPo batteries from the Adafruit shop:

The Amazon battery appears to have reverse polarity and is not compatible.
