Uninterruptible Power Supply HAT for Raspberry Pi Zero Series, 5V Stable Output, Solar Charging (5V24V), Ba-ttery Monitoring via I2C,Low-Power UPS Expansion Board

OverviewThe Pi Zero UPS HAT (B) is a compact and intelligent uninterruptible power supply board designed specifically for the Raspberry Pi Zero series, including Pi Zero, Pi Zero W, and Pi Zero 2 W. It delivers a highly integrated and developer-friendly power management solution, ideal for mobile, edge, or solar-powered Rasp-berry Pi projects. At its core, the UPS HAT integrates a multi-function charging management chip that enables simultaneous battery charging and discharging (path management), ensuringyour Rasp-berry Pi stays powered even during input power interruptions. The onboard boost converter delivers a stable 5V output, while multiple protective componentssafeguard your ba-ttery and device.

Thanks to the onboard solar input interface, the board supports 5V24V photovoltaic panels, using an MPPT (Maximum Power Point Tracking) algorithm to maximize solarcharging efficiencyperfect for environmental monitoring, outdoor sensors, or off-grid projects. The UPS HAT also includes an I2C ba-ttery monitoring chip that measures ba-ttery voltage, current, and power in real-time. Combined with an LED power indicator, users caneasily track the ba-tterys status, improving safety and system awareness. Compact yet powerful, it offers up to 9 hours of standby time with a 1500mAh ba-ttery (no peripherals connected).

It redefines the balance between small form factor and highreliability, making it an excellent fit for developers, engineers, and makers looking to build portable, resilient, and solar-friendly Rasp-berry Pi Zero systems. Whether you're powering a headless remote server, IoT gateway, or portable Python project, this Rasp-berry Pi Zero UPS module is your go-to solution for reliable, low-maintenancepower management.
