This integration transforms your Raspberry Pi into a portable device, opening up a realm of possibilities for on-the-go projects.
Key Features of PiSugar
- Uninterruptible Power Supply (UPS): PiSugar ensures your Raspberry Pi remains powered without interruption, even if the main power source is disconnected. This is crucial for applications where consistent operation is essential.
- Safe Shutdown: To protect your data, PiSugar can automatically initiate a safe shutdown when the battery reaches a low level, preventing potential data corruption.
- Real-Time Clock (RTC): With an onboard RTC, PiSugar allows your Raspberry Pi to keep track of time, even when powered off. This is particularly useful for time-sensitive applications.
- Web UI Management: PiSugar offers a user-friendly web interface, enabling you to monitor battery status, configure settings, and manage power options effortlessly.


Example Use Cases for PiSugar
- Portable Projects: Whether you’re building a handheld gaming console, a portable media player, or a mobile data logger, PiSugar provides the necessary power in a compact form factor.
- Field Data Collection: For environmental monitoring or scientific experiments conducted in remote locations, PiSugar ensures your Raspberry Pi can operate independently without reliance on external power sources.
- Educational Tools: Educators can develop interactive, battery-powered Raspberry Pi projects that students can use without being tethered to a power outlet, enhancing learning experiences.
How Does PiSugar Work?
PiSugar connects directly to the GPIO pins of the Raspberry Pi Zero series, providing a solderless and straightforward installation. Once attached, it supplies consistent power to the Raspberry Pi, and its integrated battery management system handles charging and discharging efficiently. The module can be charged via a USB connection, and with the web UI, users can monitor battery health, set up safe shutdown thresholds, and configure RTC settings.
