The KiCad project lives in the mrk-its/stm32-can-node repository on GitHub; these links point at the commit this page was built from.

Stm32-can node: common questions

What microcontroller does the Stm32-can node use?

The Stm32-can node is built around the STM32U535CEUxQ, from the STM32 family.

How big is the Stm32-can node PCB?

The Stm32-can node measures 40 × 25 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Stm32-can node?

40 components, from 24 distinct parts. The full bill of materials is listed on this page.

Where can I download the Stm32-can node design files?

From the mrk-its/stm32-can-node repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Stm32-can node design in my own project?

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

Can I test firmware for the Stm32-can node 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.
