Description

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). An LED indicates the progress of the battery charge (Green = charged, red = charging).

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. SD cards do not support this kind of joke and do not hesitate to remind us at the next start: lol: At the risk of being pampered, remember to regularly backup your SD cards. Also be careful to stop the system before turning off the power using a microswitch on the shield. There is no return Raspberry Pi, the stop is immediate.

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.
