From the project

Guided STM32WB55 Bluetooth PCB design project in KiCad, based on Phil's Lab #127.

Author: TOMAS NAVAS Date: 08/2026 Software: KiCad MCU: STM32WB55CEU6 Communication: Bluetooth Low Energy Project Type: Guided PCB Design / Hardware Design Practice

I started this project to learn the complete PCB design process in KiCad and get more comfortable understanding the hardware of STM32 boards instead of treating the microcontroller board as a black box.

STM32-WB55-Bluetooth---KiCAD-design: common questions

What microcontroller does the STM32-WB55-Bluetooth---KiCAD-design use?

The STM32-WB55-Bluetooth---KiCAD-design is built around the STM32WB55CEUx, from the STM32 family.

How many components are on the STM32-WB55-Bluetooth---KiCAD-design?

40 components, from 20 distinct parts. The full bill of materials is listed on this page.

Where can I download the STM32-WB55-Bluetooth---KiCAD-design design files?

From the Navastom3/STM32-WB55-Bluetooth---KiCAD-design repository on GitHub, which has the schematic; the links under Design files point to each one.

Can I use the STM32-WB55-Bluetooth---KiCAD-design design in my own project?

The repository has no license, so all rights stay with Navastom3. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the STM32-WB55-Bluetooth---KiCAD-design 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.
