I want to measure the voltage of a LiFePo4 battery with an ESP32 and have two options connecting the battery to the MCU: The LiFePo4 can be connected directly to the 3.3V input pin since the ESP can handle the whole range of the battery and it is commonly done I can use an LDO that regulates the v…

ESP32 ADC measurment with variable input voltage?
