About the Power Board

Power Board is an open source STM32 PCB design by SSL-A-Team, published on GitHub under the MIT license. It is a 6-layer board measuring 90 × 92.5 mm, with 192 components from 102 distinct parts.

Its main chip is the STM32G030C8TX, from the STM32 family. Other key parts include the SK9822, LM5069, LTC2955-2, LMR14050 and TLV70033_SOT23-5. By type, the board carries 76 resistors, 55 capacitors, 17 diodes, 10 ICs, 9 connectors and 6 transistors.

From the project

circuit board design files, gerbers, and circuit analysis

All current board releases use KiCad 7.X.

See releases for competition production files. Our releases include known bug documentation, and the confirmed gerber, BoM, and CPL files sent to fab so you know you're looking and ordering what we did. Releases are accompanied by a tagged commit, for all editable project files used to generate the fab products.

For complex boards like control and kicker, we include spice models and python files that compute any relevant values from datasheets, and including documented references and links to needed formulations.

Power Board: common questions

What microcontroller does the Power Board use?

The Power Board is built around the STM32G030C8TX, from the STM32 family.

How big is the Power Board?

The Power Board measures 90 × 92.5 mm, has 6 copper layers and is 1.6 mm thick.

How many components are on the Power Board?

192 components, from 102 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 Power Board design files?

From the SSL-A-Team/electrical repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Power Board design in my own project?

Yes, under the terms of its MIT license, which SSL-A-Team chose for the repository.

Can I test firmware for the Power Board 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.
