NiMH Battery Shield

Make your project autonomous with this rechargeable battery pack. This product includes a set of standard AAA rechargeable batteries that you will find in any shop. Simply plug in the batteries and recharge them via the USB-C connector.

• STAT LED (blue): ON when charging, OFF when fully charged or not charging, BLINKING when there is an error.
• LOW LED (red): ON when battery is low and about to switch off.

Good to know:
– Also compatible with Arduino Uno, Duemilanove, Mega, Leonardo and Due – basically any Arduino-pinout-shaped Arduino as only the GND and 5V pins are used.
– USB-C cable is not included, which is needed to charge the battery from your laptop or a wall adapter. If you don’t have you can get here our USB-C Cable.
– There’s currently a known misbehavior on the board, the STAT LED (blue) doesn’t turn OFF after charge is completed, unless you move the switch ON/OFF once after the battery is fully charged. We apologize for the inconvenience.
