This project is the hardware part of the superior UPS-2 project https://github.com/ECOM-Engineering/UPS-2_Uninteruptible-Power-Supply.git .

If you are looking for a simple power-down switch, please refer to the sshut** project https://github.com/ECOM-Engineering/Raspberry-Shutdown.git .

UPS-2 hardware builds an uniterruptible, efficient power supply with a wide input range. There are no glitches during switching and very low power dissipation resulting in cool operation.

UPS-2 PowerSupply HW: common questions

What microcontroller does the UPS-2 PowerSupply HW use?

The UPS-2 PowerSupply HW is built around the STM32G030FX, from the STM32 family.

How big is the UPS-2 PowerSupply HW PCB?

The UPS-2 PowerSupply HW measures 65 × 56.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the UPS-2 PowerSupply HW?

59 components, from 39 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the UPS-2 PowerSupply HW design files?

From the ECOM-Engineering/UPS-2_PowerSupply_HW repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the UPS-2 PowerSupply HW design in my own project?

It is published under Custom license, which limits how it may be reused; read the license before building on it.

Can I test firmware for the UPS-2 PowerSupply HW without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
