Title:
Introducing My New STM32F030CCT6 Development Board – Compact, Practical, and Fully Custom Designed

Hello everyone,

I’m excited to share my next embedded project with the community:
a custom development board based on the STM32F030CCT6 microcontroller.

This design follows my recent RP-series projects, and the goal this time is to create something compact, practical, and ideal for learning and prototyping within the STM32 ecosystem.

:wrench: Project Overview

The board is based on:

Microcontroller: STM32F030CCT6
(48 MHz ARM Cortex-M0, 256 KB Flash, 32 KB RAM)

Power Input: USB-C port with proper CC resistors

Voltage Regulation: On-board 3.3 V LDO regulator

Programming Interface: Standard SWD 1×4 header

GPIO Access: Full exposure of all MCU pins

Form Factor: Small, clean, and beginner-friendly

PCB: 4-layer design for stable routing and noise reduction

The idea is to build a board that is:

Easy for beginners to start with

Suitable for education and prototyping

Reliable and electrically clean

Flexible for different firmware development workflows (HAL, LL, or bare-metal)

:high_voltage: Why STM32F030CCT6?

Very cost-efficient

Strong toolchain support (CubeMX, HAL/LL)

Widely available

Great for learning ARM microcontrollers

Robust peripherals and good performance for its class

:hammer_and_wrench: Current Progress

I’m currently working on:

Finalizing the schematic

Verifying the MCU footprint

USB-C power and protection circuitry

SWD header placement

Proper decoupling capacitor layout

Reset / BOOT configuration pins

Once PCB routing is complete, I will share:

3D renders

Gerber previews

Test results

Example firmware and documentation

:bullseye: Project Goals

:check_mark: Provide a clean open-source STM32F0 development board
:check_mark: Share complete documentation and KiCad/EasyEDA files
:check_mark: Make an accessible board for students and hobbyists
:check_mark: Offer a reference design for anyone exploring STM32 for the first time

If anyone has feedback or recommendations — especially regarding layout best practices, USB-C power design, or SWD accessibility — I would be glad to hear your insights.

Thank you to the DigiKey community for the continuous inspiration and support.
I look forward to sharing more updates soon!

Best regards,
Sikwal

Hello everyone,

Just a quick update —
I’m excited to share that I’ve officially started working on the new STM32F030CCT6 Development Board project.

This will be a compact and practical board designed for learning, prototyping, and exploring the STM32 ecosystem.
I will post more details soon, including schematic progress, power design, and early layout work.

Thank you all for the great support so far.
More updates coming soon!

Best regards,
Sikwal
