PowerBoost is the perfect power supply for your portable project! This little DC/DC boost converter module can run from 1.8V batteries or higher, and convert that voltage to 5.2V DC for running your 5V projects.

Battery input for the boost converter. Adafruit states BAT can range from 1.8V to 5V and recommends short battery wires.
Power ground. Adafruit states the boost converter is not isolated, so input ground and output ground are the same.
Boosted output. Adafruit states the running output is approximately 5.2V and may dip toward 5V as current draw rises over 500mA.
Enable input. Adafruit states EN is pulled high to VBAT by default and the booster turns off when EN is connected to ground.
Low Battery Output. Adafruit states LBO is pulled high to BAT by default and drops to 0V when low battery is detected under 3.2V.
