STM32F401CC Black Pill Development Board

ARM Cortex-M4 Core with FPU: Powered by the STM32F401CCU6 / STM32F401CC 32-bit microcontroller running at up to 84 MHz, featuring a Hardware Floating Point Unit (FPU) and DSP instruction set for efficient mathematical computations and real-time processing.

Onboard Flash & SRAM Memory: Equipped with 256 KB of embedded Flash memory and 64 KB of SRAM, providing optimal capacity for medium-scale embedded systems, sensor acquisition nodes, and RTOS environments.

Modern USB Type-C Interface: Features a durable USB Type-C port for 5V DC power supply, serial communication, and Direct Firmware Upgrade (DFU) bootloader flashing without external programmers.

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

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

Module Construction: Built on a double-sided black FR-4 glass epoxy PCB with surface-mount components, onboard 25 MHz primary crystal, and 32.768 kHz RTC crystal.

Operating Voltage & Logic: Operates logic lines at 3.3V DC (with 5V-tolerant GPIO pins). Powered via USB Type-C (5V DC) or through external VIN headers (4.5V to 9V DC).

Handling Precautions: Practice standard electrostatic discharge (ESD) handling safety. Double-check pin alignment and voltage levels before making connections to external breadboards or hardware.

Environmental Limits: Operating temperature range spans -40°C to +85°C. Protect from liquid moisture, conductive metal dust, and accidental short circuits during breadboard prototyping.

Cost-Effective Upgrade to 32-Bit ARM: Position as an accessible, high-efficiency upgrade over standard 72 MHz Cortex-M3 boards, delivering DSP power and USB Type-C connectivity at an economical price.

Ideal Platform for Maker & Educational Projects: Highlight its hardware FPU capabilities and compact footprint for learning 32-bit ARM development, digital signal filtering, and sensor processing.

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 Prototyping Workbenches: Excellent choice for university microelectronics labs, custom IoT hardware design, and embedded firmware development.
