and what ever you do :astonished: ,DO not Hook Up Battery BACKWORDS.
Xiao Gets “VERY HOT” especially if the USBC is plugged in. It will still work but won’t ever charge another battery again. Don’t ask how I have come by this knowledge :wink:
specifically a Xiao BLE Sense , formerly know as the “Xiao BLE Nrf52840 Sense”
I still use it but it doesn’t charge batteries anymore.
