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.
Pinout
- USB
On-board USB power/charge input; Particle docs state the Power Shield can power the Particle device and charge the LiPo from USB.
Type · USBVoltage · USB 5V input; charge current is set to 500mA when charging from USB per Particle docs. - DC input
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.
Type · PowerVoltage · 7 to 20V DC operating input, current consumption 1.2A max from non-USB DC sources per Particle docs. - LiPo JST
3.7V LiPo battery connector charged by the shield and used by the power-management circuit.
Type · UnknownVoltage · 3.7V LiPo battery; Adafruit product page states the shield ships with a 3.7V 2000mAh Li-Po battery. - D0SDA
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.
Type · GPIO, I2CVoltage · Particle I2C logic level on Photon/Core shield interface. - D1SCL
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.
Type · GPIO, I2CVoltage · Particle I2C logic level on Photon/Core shield interface. - STAT1
Blue charger status LED; Particle docs list STAT1/STAT2 combinations for precharge, fast charge, charge done, suspend, fault, and sleep states.
Type · Unknown - STAT2
Red charger status LED; Particle docs list STAT1/STAT2 combinations for precharge, fast charge, charge done, suspend, fault, and sleep states.
