This 18650 battery shield is used to charge and power an Arduino, ESP8266, ESP32 expansion board via the USB output (type A) or directly using the 6 outputs (soldering pin) available on each side of the board (5V or 3V). The shield has a charging circuit (not protected against polarity inversions).

According to the product designation, this card seems to power a mini PC Raspberry Pi type. It is more an optimization of keywords to be visible in the search results than a real power solution. In theory, it should also allow to power the Raspberry Pi and all other mini PCs (Orange Pi, Banana Pi, Odroid …) that have a USB OTG port. Be careful however to buy a high capacity LiFePO battery. The card has no output to measure the battery charge level. It will therefore be necessary to be careful to measure the service life for a complete charge in order to avoid any sudden stop of the system.

The shield has a fairly basic charge control circuit. It is clear to stay polarity. Any inversion of polarity may cause the destruction of the charging circuit. The board has a micro USB connector to charge the battery.

We can feed a development card or any device with a USB port. For this, we have a type A USB output. The maximum intensity delivered is not indicated. It is probably 4A as the side connectors. We also have 3 connectors to deliver 3V up to 1A and 3 connectors to deliver 5V up to 2A. The 6 connectors are on each side of the board. It will directly solder the power supply or solder a header at a pitch of 2.54mm beforehand.
