Particle Power Shield with Headers
Li-Ion/Li-Po battery management shield for the Particle Photon, built around the MCP73871 controller. Simultaneously powers the Photon and charges a connected battery; battery level is monitorable via the Photon.

On-board USB power/charge input; Particle docs state the Power Shield can power the Particle device and charge the LiPo from USB.
External DC supply input for powering the Particle device and charging the 3.7V LiPo battery; Particle docs state DC is preferred over USB when both are present.
3.7V LiPo battery connector charged by the shield and used by the power-management circuit.
Particle D0 I2C data line used by the MAX17043 fuel-gauge chip; Particle docs say avoid using D0 as GPIO because it will interfere with the fuel gauge.
Particle D1 I2C clock line used by the MAX17043 fuel-gauge chip; Particle docs say avoid using D1 as GPIO because it will interfere with the fuel gauge.
Blue charger status LED; Particle docs list STAT1/STAT2 combinations for precharge, fast charge, charge done, suspend, fault, and sleep states.
Red charger status LED; Particle docs list STAT1/STAT2 combinations for precharge, fast charge, charge done, suspend, fault, and sleep states.
