About the My-Own-UPS-HAT-for-Raspberry-Pi-Zero

My-Own-UPS-HAT-for-Raspberry-Pi-Zero is an open source PCB design by harshverma27, published on GitHub. It is a 2-layer board measuring 65 × 30 mm, with 31 components from 27 distinct parts.

Other key parts include the TP4056-42-ESOP8, DW01A and TPS61236PRWLR. By type, the board carries 10 resistors, 6 capacitors, 5 connectors, 3 ICs, 3 transistors and 2 diodes.

It belongs with the power & battery and dev boards & breakouts designs in this gallery.

From the project

This project is step by step explanation of how I created my own UPS HAT for Pi Zero 2/2W

This project is a budget-friendly UPS (Uninterruptible Power Supply) designed specifically for the Raspberry Pi Zero 2.

I built this because I personally use a Pi Zero 2, and I needed a reliable battery backup (UPS) for it. Most ready-made UPS solutions available are either:

Too expensive Overkill for Pi Zero * Poorly designed or unreliable

So instead of buying one, I designed my own UPS PCB from scratch.
