PiSugar Battery for Raspberry Pi zero

The PiSugar Battery project establishes a portable, untethered power delivery system for a Raspberry Pi Zero 2 W. At its core, the PiSugar battery module physically mounts directly to the underside of the Raspberry Pi Zero, utilizing spring-loaded pogo pins to make secure electrical contact with the Pi's 5V and ground pins without requiring any permanent soldering. This configuration supplies regulated DC power directly to the single-board computer. To interface with the system configuration, users leverage software packages such as sugar-wifi-conf, Python or shell scripts, and a Web Bluetooth client. The I2C protocol is typically utilized for communication between the battery management system and the Raspberry Pi, enabling the host computer to monitor vital telemetry data such as battery voltage, charge state, and power status. The custom 3D-printed case mechanically houses both the Raspberry Pi and the PiSugar module together, forming a unified, rigid enclosure that protects the internal electronics while maintaining access to ports and pins. By integrating the hardware module with appropriate scripting, the system enables autonomous power management, safe shutdowns upon low battery conditions, and wireless setup routines suitable for remote field telemetry and mobile deployment.
