    Пока не проверял. Выглядит хорошо.

    Das Anschließen dieser Platine ist selbst für Laien problemlos. Leider ist beim Versand ein kleines Plastikteil für den Anschluss der externen Batterie abgebrochen. Was allerdings keine Beeinträchtigung der Nutzung ist.

    Este Wemos tiene buena calidad. Es el indicado para los dispositivos IoT que requieran batería. Se agradece que sus pines vengan sin montar porque da más opciones de montaje y sería bueno que el de la batería también venga sin montar pero no es un problema. Viene todo bien indicado en la serigrafía con su opción de J1 para 1A y 0.5A incluso tiene pads para poder usar los D+D- del usb lo cual está muy bien. Recomiendo probarlos apenas lleguen por si hay que reclamar ya que claramente se indica

    That little shield works perfectly with my WiFi Scanner. Small size, but powerful :)

    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
