STM32 POC Board: common questions
What microcontroller does the STM32 POC Board use?
The STM32 POC Board is built around the STM32G474RETX, from the STM32 family.
How big is the STM32 POC Board?
The STM32 POC Board measures 50 × 50 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the STM32 POC Board?
36 components, from 22 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 STM32 POC Board design files?
From the ParadigmEngineering/aks-2026-hardware 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 STM32 POC Board design in my own project?
The repository has no license, so all rights stay with ParadigmEngineering. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the STM32 POC 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.
