| 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. | ||
