XIAO 52840 Sense + Grove Shield - Battery Monitoring?

Products & Technology XIAO
#1

I am using a XIAO 52840 Sense with a Grove Shield with Battery Management chip ( Grove Shield for XIAO with battery management chip | Seeed Studio Wiki ) and am wondering if there is a way to monitor the battery voltage when using the shield with the battery connected to the shield?

If I monitor PIN_VBAT it just seems to give a constant 3.3v, so I can’t tell if my battery is getting low.

Is there a way to do this?

The Grove Shield battery is not connected to the XIAO port, so I don’t think it is possible to monitor the battery voltage. If you want to monitor it on XIAO, you need to divide the battery voltage appropriately and connect it to the port.
PIN_VBAT can read the battery voltage connected to the pad on the back of the XIAO nRF52840.
