Test project: common questions

What microcontroller does the Test project use?

The Test project is built around the STM8S003F3P6TR, from the STM32 family.

How big is the Test project PCB?

The Test project measures 78.8 × 87.9 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Test project?

38 components, from 14 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 Test project design files?

From the crikeyk/XMAS_2025 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 Test project design in my own project?

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

Can I test firmware for the Test project 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.
