About the Mcustm32f405 PCB

Mcustm32f405 is an open source STM32 PCB design by 11philip22, published on GitHub. It is a 2-layer board measuring 76.2 × 50.8 mm, with 40 components from 23 distinct parts.

Its main chip is the AMS1117-3.3, from the STM32 family. Other key parts include the STM32F405RGTx. By type, the board carries 16 capacitors, 6 resistors, 4 connectors, 4 jumpers, 4 diodes and 2 ICs.

It belongs with the dev boards & breakouts designs in this gallery.

From the project

KiCad design for an STM32F405 development board with USB-C.

A KiCad microcontroller board built around the STM32F405RG, with USB-C, two 2×20 expansion headers, and onboard 3.3 V regulation. The board includes a 16 MHz crystal, reset and BOOT0 buttons, and a user LED; GPIO, power, and SWD signals are available on the expansion headers.

Based on the STM32World MCUSTM32F405 design by Lars Boegild Thomsen; see the upstream board documentation for background.

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 1.2 mm thick.

How many components are on the Mcustm32f405?

40 components, from 23 distinct parts. The full bill of materials is listed on this page.

Where can I download the Mcustm32f405 design files?

From the 11philip22/mcustm32f405 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Mcustm32f405 design in my own project?

The repository has no license, so all rights stay with 11philip22. Use it as a reference, and ask the author before reusing the design.

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.
