About the STM32F401RE-Dev-Board-Design

STM32F401RE-Dev-Board-Design is an open source STM32 PCB design by colonelblacc, published on GitHub. It is a 2-layer board measuring 100 × 100 mm, with 35 components from 16 distinct parts.

Its main chip is the STM32F401RETx, from the STM32 family. Other key parts include the AMS1117-3.3. By type, the board carries 14 capacitors, 8 resistors, 7 connectors, 2 ICs, 1 crystal and 1 switch.

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

From the project

Custom two-layer STM32F401RE development board designed in KiCad, featuring USB-C, SWD debugging, UART, SPI, I²C, GPIO expansion, regulated 3.3 V power, external crystal and user-interface circuitry.

This repository covers the complete design lifecycle:

The schematic is divided into functional blocks:

- STM32F401 — Central MCU with all peripheral nets routed - Power Supply — AMS1117-3.3 LDO with bulk and decoupling capacitors - USB-C Connector — With 5.1k CC1/CC2 pull-down resistors (R7, R8) - Crystal — 24 MHz with 22pF load capacitors C12, C13 - Header Breakouts — UART, SPI, I2C, GPIO, SWD - Mounting Holes — H1–H4 (M2.5, 2.7mm diameter)
