St link design files

The KiCad project lives in the lbthomsen/st-link repository on GitHub; these links point at the commit this page was built from.

St link: common questions

What microcontroller does the St link use?

The St link is built around the STM32F103C8, from the STM32 family.

How big is the St link PCB?

The St link measures 31 × 15 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the St link?

32 components, from 21 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 St link design files?

From the lbthomsen/st-link 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 St link design in my own project?

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

Can I test firmware for the St link 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.
