STM32F401CCU6 Black Pill Development Board

ARM Cortex-M4 Core with FPU: Powered by the STM32F401CCU6 32-bit microcontroller running at up to 84 MHz, featuring a Hardware Floating Point Unit (FPU) and DSP instruction set for efficient math and signal processing operations.

Onboard Flash & SRAM Memory: Equipped with 256 KB of embedded Flash memory and 64 KB of SRAM, offering ideal capacity for medium-scale embedded projects, sensor node processing, and RTOS environments.

Modern USB Type-C Connector: Features a durable USB Type-C port supporting 5V DC power input, serial communication, and Direct Firmware Upgrade (DFU) bootloader programming.

Rich Peripheral Interfaces: Exposes full GPIO pin access with hardware support for SPI, I2C, USART, PWM timer outputs, and a 12-bit Analog-to-Digital Converter (ADC).

Dedicated SWD Header & Onboard Controls: Includes a 4-pin Serial Wire Debug (SWD) header for fast ST-LINK/V2 debugging, user and reset push buttons, and power/status LED indicators.

Module Construction: Built on a double-sided black FR-4 PCB with high-density SMD components, onboard 25 MHz primary crystal oscillator, and 32.768 kHz RTC crystal.

Operating Voltage & Logic: Logic operates at 3.3V DC (with 5V-tolerant I/O pins). Powered directly via USB Type-C (5V DC) or through external VIN pin headers (4.5V to 9V DC).

Handling Precautions: Practice standard electrostatic discharge (ESD) handling safety. Verify pin alignments and power levels prior to connecting to breadboards or debuggers.

Environmental Limits: Operating temperature range spans -40°C to +85°C. Keep protected from moisture, metallic dust, and short circuits during testing.

Cost-Effective Step-Up from Cortex-M3: Position as an accessible, high-efficiency upgrade over standard 72 MHz Cortex-M3 boards, delivering DSP power and USB Type-C convenience at an economical price.

Great Choice for Educational & Maker Projects: Highlight its FPU capability and compact form factor for learning 32-bit ARM development, DSP filtering, and sensor data acquisition.

Recommended Cross-Sell Add-ons: Pair with ST-LINK/V2 Debuggers, USB Type-C Data Cables, OLED Display Modules (I2C/SPI), and Breadboard Jumper Wires.

Essential for Rapid Prototyping Benches: Perfect budget-friendly platform for university electronics labs, IoT hardware design, and custom embedded device development.
