Mcu block: common questions
What microcontroller does the Mcu block use?
The Mcu block is built around the STM32H745IIT6, from the STM32 family.
How big is the Mcu block PCB?
The Mcu block measures 60 × 200 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Mcu block?
27 components, from 9 distinct parts. The full bill of materials is listed on this page.
Where can I download the Mcu block design files?
From the pierrekin/buddies repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Mcu block design in my own project?
The repository has no license, so all rights stay with pierrekin. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Mcu block 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.
