    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.

    Ok. Charges the Li-ion battery to 4.0V and not to 4.2V. Only USB connector for charging, but you can use one side of the R330 as + and GND for - to charge

    Note, this shield provides the 5V but not the 3.3V for the D1 mini ESP8266 motherboard. 3.3V is made by the D1 board itself from the supplied 5V.
