MCUSTM32F405: common questions

What microcontroller does the MCUSTM32F405 use?

The MCUSTM32F405 is built around the AMS1117-3.3, from the STM32 family.

How big is the MCUSTM32F405 PCB?

The MCUSTM32F405 measures 76.2 × 50.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the MCUSTM32F405?

35 components, from 22 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the MCUSTM32F405 design files?

From the STM32World/hardware repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the MCUSTM32F405 design in my own project?

It is published under Custom license, which limits how it may be reused; read the license before building on it.

Can I test firmware for the MCUSTM32F405 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.
