STM32x: common questions
What microcontroller does the STM32x use?
The STM32x is built around the STM32F411CCU6TR, from the STM32 family.
How big is the STM32x PCB?
The STM32x measures 39.6 × 49.9 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the STM32x?
30 components, from 19 distinct parts. The full bill of materials is listed on this page.
Where can I download the STM32x design files?
From the MTubbin/STM32x repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the STM32x design in my own project?
The repository has no license, so all rights stay with MTubbin. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the STM32x 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.
