STM32F401CCUx core board

Overview

Introduction

The compact STM32F401CCUx core board can be easily used on a breadboard.

characteristic

Small in size, it can be easily embedded in other projects or used for performance verification on breadboards.
Jumpers and resistors are used to select whether the USB function uses UART or built-in USB-FS.
Two LEDs: one for power indication and one for user-defined use
The user LED is driven by MOS to minimize the impact on the IO port signal.
3 buttons: including a reset, a BOOT selection and a user-defined button (PA0)
The user-defined button is connected to PA0 and can be used as a standby wake-up.
All IO ports are introduced
SWD debugging interface
