I don't think so because it says "Applying more than 3.3V on any pin will damage the board.". I don't really want to try ! Do you confirm ?
I'm feeding my MkrFox1200 a 3.7V Lipo, works fine
Can you please confirm that it still works fine? A fully charged single LiPO cell will provide 4.2V, is this still fine with your board? I totally need to find a rechargeable solution for a MKRFOX, and then apply a solar panel to charge itThanks
