About the Stm32....c breakout

Stm32....c breakout is an open source STM32 PCB design by electroniceel, published on GitHub under the CC-BY-4.0 license. It is a 2-layer board measuring 25.4 × 50.8 mm, with 59 components from 31 distinct parts.

Its main chip is the STM32F103CB, from the STM32 family. Other key parts include the XC6204B332MR and IP4220CZ6. By type, the board carries 16 capacitors, 12 resistors, 5 connectors, 3 ICs, 3 diodes and 3 inductors.

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

From the project

A breakout module for STM32 microcontrollers in LQFP48 and UFQFPN48 footprint.

STM32....C (LQFP48 and UFQFPN48) Breakout Module ================================================

A breakout module for STM32 microcontrollers in LQFP48 and UFQFPN48 footprint.

Focus on small footprint and direct access to most pins. 40 pins broken out, organized as two single row headers in 2.54mm pitch Footprints for USB-B (THT) or Micro-USB (SMT) Header Provides a 8 pin Micro-MaTch header for easy access to SWD and UART. Pushbutton for Reset (press 3 seconds). Onboard LDO regulator (standard SOT-23-5) can be used for VDD and VDDA, just VDD or bypassed completely. USB VBUS (5V) is…

Stm32....c breakout: common questions

What microcontroller does the Stm32....c breakout use?

The Stm32....c breakout is built around the STM32F103CB, from the STM32 family.

How big is the Stm32....c breakout?

The Stm32....c breakout measures 25.4 × 50.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Stm32....c breakout?

59 components, from 31 distinct parts. The full bill of materials is listed on this page.

Where can I download the Stm32....c breakout design files?

From the electroniceel/stm32....c-breakout repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Stm32....c breakout design in my own project?

Yes, under the terms of its CC-BY-4.0 license, which electroniceel chose for the repository.

Can I test firmware for the Stm32....c breakout 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.
