DFR0528 UPS for Raspberry Pi Zero
Overview
The DFR0528 is an uninterruptible power supply expansion board designed specifically for the Raspberry Pi Zero form factor. It integrates a Maxim MAX17043 fuel gauge IC and a charging circuit to provide regulated 5V power from a single-cell lithium battery.
Why Choose This Part
The board features an auto-switching path that allows the system to charge the battery and power the Pi simultaneously. It provides up to 2A of output current at 5V, accommodating the Pi Zero along with several peripherals, and includes built-in protection against over-heating and backflow.
Applications
Key Specifications
Getting Started
Mount the board directly to the Raspberry Pi Zero GPIO header and connect a 3.7V lithium polymer battery. Use the I2C interface to communicate with the MAX17043 fuel gauge for accurate battery percentage and voltage monitoring via standard Linux libraries.
