Easy way to power your Photon module with a Lithium Polymer (LiPo) battery
JST connector for your single-cell LiPo battery
Level shifting between 3.3V and 5V
Compatible with the Photon and the Core
The SparkFun Photon Battery Shield provides you with an easy way to power your Photon module with a Lithium Polymer (LiPo) battery. Not only can the Battery Shield power your Photon, but you will also be able to charge a LiPo battery through it. The board comes with a JST connector for your single-cell LiPo battery and utilizes the Photon's on-board micro-USB connector for the charge input.
This battery shield uses a MCP73831 for LiPo charging and a MAX1704X for fuel gauging. This is a very simple shield for your Photon to provide it basic and on-the-go power wherever and whenever you might need it! The SparkFun Photon Battery Shield comes with the headers already soldered on, so you can plug and play!
Since the I/O banks can operate between 1.2V and 3.6V (5.5V tolerant) independent of both the core and each other, this device can also work as a level-shifter. The SX1509 breakout makes it easy to prototype so you can add more I/O onto your Arduino or I/O limited controller.
