PiSugar 3 Air - Modular UPS Board for Raspberry Pi Zero(Battery Not Included)

Raspberry Pi Zero UPS - Batteryless Version

PiSugar 3 Air is the high-flexibility edition of the PiSugar 3 series, specifically designed for Raspberry Pi Zero / Zero W / Zero 2W.

Instead of a built-in battery, PiSugar 3 Air is designed as a standalone UPS power management board featuring a standard PH2.0 connector. This gives you the ultimate flexibility to pair it with any 3.7V Li-ion or Li-Po battery that perfectly fits your project's capacity and space requirements. While offering a more adaptable hardware layout, it retains all the advanced power management and RTC (Real-Time Clock) capabilities of the PiSugar 3 platform.
