Hello all, I'm doing a project using 4 equal boards (lolin32 lite clones - like image below) Within other things I've done a voltage devider to check the battery level (and for that I'm using pin VP since I saw a lot of recomendations to do so). The reason I've opened this topic is because depend…

ESP32 lolin32 pin reading differ from board to board

Hi,

real battery voltage is at 4.20v and shows correctly in the other boards (+/- 0.05V differences) but in this one shows 4.00v... meaning that when extrapolating to % it says it is arround 80% instead of 100%
