MCDODO PiSugar 3 Power Management Board for Raspberry Pi Zero W/WH

SKU CH-6J9K-GT6X5

Portable power-management board adds intelligent monitoring, multi-level protection, a real-time clock and a custom button to Raspberry Pi Zero W/WH without blocking the GPIO header

  • Product typeSingle Board Computers
  • Intelligent system monitor prevents crashes by tracking power and auto-restarting
  • Multi-level protection guards against over-voltage over-current and under-voltage faults
  • Non-intrusive back-mount design keeps GPIO header free for other HATs
  • I2C interface with configurable address enables multi-device integration
  • Built-in RTC and custom button allow scheduled wake-ups and flexible power control

Power Management for Pi Zero

The MCDODO PiSugar 3 is a power management board designed for the Raspberry Pi Zero W and WH models. It provides intelligent system monitoring that tracks power conditions and triggers automatic restarts to prevent crashes. Multi-level protection includes over-voltage, over-current, and under-voltage safeguards. The board installs on the back of the Zero series without blocking the GPIO header.

Makers needing portable uptime

This board suits builders creating portable or headless projects such as a Pwnagotchi device who need safe battery management and unattended reliability. The non-intrusive design keeps the GPIO header free for additional HATs or sensors. Buyers who require a power solution for larger Raspberry Pi models such as the Pi 3 or Pi 4 should look at other options.

I2C communication and RTC

The board communicates with the Raspberry Pi over an I2C interface with a configurable address for integration into multi-device buses. A built-in real-time clock enables scheduled wake-up functions and accurate timekeeping without a network connection. A customizable hardware button provides flexible manual control over power states.

Questions about this item

Should I pick the PiSugar 3 for a Pi Zero W or a Pi Zero WH?

The board fits both the Raspberry Pi Zero W and Zero WH without blocking the GPIO header so either model works.

What does the intelligent system monitor actually do once the board is installed?

It continuously tracks power conditions and automatically restarts the Pi if voltage or current drift out of safe limits preventing unattended crashes.

How does the I2C interface limit what I can connect alongside this board?

The board uses a configurable I2C address so it shares the bus with other HATs without address conflicts.
