Power Shield

The Power Shield, as the name implies, allows the Particle device to be powered from different

types of power sources. The shield has an intelligent battery charger and power management unit

along with a wide input voltage regulator and an I2C based fuel-gauge. You can power a Particle

device with either a USB plug or a DC supply of anywhere from 7 to 20VDC and charge a

3.7V LiPo

battery

all at the same time.

The system switches in between the different power sources automatically, reducing the charge and

discharge cycle stress on the battery. The fuel gauge allows you to monitor the battery's state-of-

charge (SOC), allowing it to notify the user remotely and take preemptive actions when necessary.
