STM32: common questions

What microcontroller does the STM32 use?

The STM32 is built around the STM32U545RETxQ, from the STM32 family.

How big is the STM32 PCB?

The STM32 measures 29.6 × 29.6 mm, has 4 copper layers and is 1.6062 mm thick.

How many components are on the STM32?

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

Where can I download the STM32 design files?

From the ihsan92UM/Project-work 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 design in my own project?

The repository has no license, so all rights stay with ihsan92UM. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the STM32 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.
