 The LiPo Charger and Boost Shield Kit allows you to use and charge single cell LiPo batteries with the Digispark development board. The LiPo Charger and Boost Shield boosts a 2-4.5v supply to 5v and connects directly to the Digispark. When the on-board switch is flipped it draws 5v from the Digispark and charges the attached single cell LiPo battery. The LiPo Charger and Boost Shield Kit allows you to use and charge single cell LiPo batteries with the Digispark development board.

 +Insert either the 2k or 10k resistor into the Prog spot. Use the 2k for a charge rate of 500ma, use the 10k for a rate of 100ma. If you don't know which to use, we recommend the 10k, it will result in a slower charge, but with less heat and less power draw from the USB/​Digispark. Solder the leads and clip off the excess.
