The KiCad project lives in the aatishh/cantact-hw- repository on GitHub; these links point at the commit this page was built from.

Cantact hw-: common questions

What microcontroller does the Cantact hw- use?

The Cantact hw- is built around the STM32F042C6T6, from the STM32 family.

How many components are on the Cantact hw-?

37 components, from 22 distinct parts. The full bill of materials is listed on this page.

Where can I download the Cantact hw- design files?

From the aatishh/cantact-hw- repository on GitHub, which has a netlist; the links under Design files point to each one.

Can I use the Cantact hw- design in my own project?

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

Can I test firmware for the Cantact hw- 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.
