MCU Board: common questions

What microcontroller does the MCU Board use?

The MCU Board is built around the STM32H743IIT6, from the STM32 family.

How big is the MCU Board?

The MCU Board has 6 copper layers and is 1.6 mm thick.

How many components are on the MCU Board?

239 components, from 31 distinct parts. The full bill of materials is listed on this page.

Where can I download the MCU Board design files?

From the dirktjantele/CasualNoises repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the MCU Board design in my own project?

Yes, under the terms of its GPL-3.0 license, which dirktjantele chose for the repository.

Can I test firmware for the MCU Board 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.
