Control Board POC: common questions

What microcontroller does the Control Board POC use?

The Control Board POC is built around the STM32G474RETX, from the STM32 family.

How big is the Control Board POC?

The Control Board POC measures 62 × 55 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Control Board POC?

53 components, from 36 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 Control Board POC 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 Control Board POC 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 Control Board POC 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.
