USB LiPo Charger
This small circuit can recharge in an extremely simple way Li-Po and Li-Ion cells. Using a jumper with two positions you can select two possible values for the charging current, 100mA and 500mA; the correct value should be chosen in consultation with the characteristics of the battery.
The board includes the charging circuit, the JST connector for the battery, and a LED that indicates the in progress charging status.
If the JST connector is not suitable, you can take the voltage for the battery even from a 2-pin strip connector that eventually can be connected to a cable adapter for your battery.
The power is taken from the mini-USB connector that can be connected to any PC or mobile phone chargers.
