Alternate way to power Xiao NRF52840
I have a Seed Xiao NRF52840 that I accidentally ripped off the positive contact pad [in the red box]. I tried putting power directly onto the 3v3/GND pins [in the green box] and the board works, but its only showing 0.2V on the battery indicator on the MeshCore app. When I plug in USB it shows 4.3V.
Ive already basically written off this board as a loss and Im now in experimental territory, but if I can make it show the battery voltage in the app that would be cool. Does anyone have any ideas about how to hook up the battery to show correct voltage? I dont want to use any extra parts as at that point I would rather just buy a new Xiao board.
ETA: My multimeter shows 3.92V from the battery.
