Pi shim power: common questions

What microcontroller does the Pi shim power use?

The Pi shim power is built around the GPIO, from the Raspberry Pi family.

How big is the Pi shim power PCB?

The Pi shim power measures 24.1 × 66 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Pi shim power?

3 components, from 3 distinct parts. The full bill of materials is listed on this page.

Where can I download the Pi shim power design files?

From the eshazen/StudentProjects2025 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Pi shim power design in my own project?

The repository has no license, so all rights stay with eshazen. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Pi shim power without the hardware?

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