STM32F103C8T6 ARM Mini System Development Board

High-Performance 32-Bit ARM Cortex-M3 Core: Powered by the STM32F103C8T6 microcontroller running at up to 72 MHz CPU clock frequency, offering high execution speed for real-time control and signal processing tasks.

Onboard Flash & SRAM Memory: Equipped with 64 KB of embedded Flash memory and 20 KB of SRAM, providing ample space for custom embedded firmware and complex data buffering.

Versatile Serial Debugging & SWD Header: Features a dedicated 4-pin Serial Wire Debug (SWD) header interface, allowing fast in-circuit programming and real-time debugging with ST-LINK/V2, J-Link, or generic debuggers.

Rich Peripheral Interfaces: Includes multiple SPI, I2C, USART, ADC channels, and PWM-capable timers for seamless interfacing with sensors, OLED/LCD displays, motor drivers, and communication modules.

Integrated Power Regulation & USB Connectivity: Built-in 3.3V low-dropout (LDO) voltage regulator powered via standard Mini-USB/Micro-USB port, supplying clean power to the board and connected external sensors.

Module Construction: Built on a double-sided FR-4 glass epoxy printed circuit board (PCB) with high-density surface-mount components, dual-row 2.54mm header pads, and an onboard 8 MHz main crystal oscillator.

Operating Voltage & Logic: Operates logic lines at 3.3V DC (with many 5V-tolerant I/O pins). Input power supplied via USB (5V DC) or external V_N pin (4.5V to 9V DC).

Handling Precautions: Observe standard electrostatic discharge (ESD) safety procedures. Verify proper jumper positions (BOOT0 / BOOT1) before uploading code via serial or SWD interfaces.

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

Essential Workbench Staple for ARM Developers: Position as the definitive, affordable entry-level 32-bit development board for students, makers, and embedded software engineers stepping up from 8-bit microcontrollers.

Unmatched Flexibility for Prototyping: Highlight its compact footprint and dual-sided GPIO pins, making it perfect for custom IoT gateways, robotics controllers, and rapid hardware-in-the-loop testing.

Recommended Cross-Sell Add-ons: Pair with ST-LINK/V2 Debuggers, OLED Display Modules (I2C/SPI), FTDI USB-to-TTL Serial Converters, and Breadboard Jumper Wire Sets.

Ideal for University & Industrial Labs: Must-have platform for academic microelectronics courses, embedded system prototyping, and low-cost IoT sensor node deployment.
