This board is a charge Shield for a single 18650 Battery.

It can provide 3V (1A) or 5V (2A) output - through the solderable ports on the side of the board.

The board cannot only be used to provide power from the battery, but also to charge the battery - this makes it great to use in projects with a built-in battery.
It is charged through a Micro USB port and features a Type-A USB port for output.
The charge is at 0.5A, which allows using a smaller input source (e.g. solar panel) and accepts input range from 5-8V.

A green/red LED indicates the charging status.

IMPORTANT: Be careful of "+" and "-" being wired correctly. Incorrect wiring or putting the battery in the wrong way round can damage the circuit.
