Very useful for adding a a battery option to a D1 Mini. This one does not have the 130k resistor and jumper option to connect the battery positive to the A0 ADC input to read the battery level. This is easily done by soldering a 130k resistor directly between the battery + connector and A0. This gives an ADC max input range of 4.5V which is enough for a Lipo battery. To get the battery voltage, read the ADC input and and multiply by 4.39 to get the battery voltage in millivolt.
