Be gentle when plugging and unplugging from the USB connector. Whilst the USB connector is soldered and is relatively strong, if it breaks off it can be very difficult to fix.

Battery Charger

The Expansion Board features a single cell Li-Ion/Li-Po charger. When the board is being powered via the micro USB connector, the Expansion Board will charge the battery (if connected). When the CHG jumper is present, the battery will be charged at 450mA. If this value is too high for your application, removing the jumper lowers the charge current to 100mA.
