The KiCad project lives in the Thrcot/ThormasMK2-circuit repository on GitHub; these links point at the commit this page was built from.

Line: common questions

What microcontroller does the Line use?

The Line is built around the STM32F303K8TX, from the STM32 family.

How big is the Line PCB?

The Line measures 92.2 × 92.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Line?

155 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 Line design files?

From the Thrcot/ThormasMK2-circuit 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 Line design in my own project?

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

Can I test firmware for the Line 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.
