STM32F103C8T6 ARM M3 Development Board

High-Performance 32-Bit ARM Cortex-M3 Core: Powered by the STM32F103C8T6 microcontroller running up to 72 MHz, delivering fast processing speed for real-time control applications and digital signal processing tasks.

Onboard Flash & SRAM Memory: Features 64 KB of embedded Flash memory and 20 KB of high-speed SRAM, offering adequate space for custom firmware, buffer management, and RTOS environments.

Dedicated SWD & Serial Debug Header: Includes a 4-pin Serial Wire Debug (SWD) header interface for fast, real-time in-circuit debugging, breakpoint monitoring, and flashing via ST-LINK/V2 debuggers.

Rich Peripheral Interfaces: Exposes full GPIO pin connections with hardware support for SPI, I2C, USART, PWM-capable timers, and multi-channel 12-bit Analog-to-Digital Converters (ADC).

Onboard Power Regulation & USB Connectivity: Integrated 3.3V low-dropout (LDO) voltage regulator powered via standard USB interface, along with reset button, BOOT select jumpers, and power/status LED indicators.

Module Construction: Built on a multi-layer FR-4 glass epoxy printed circuit board featuring high-density SMD components, dual-row 2.54mm pitch headers, 8 MHz main crystal, and 32.768 kHz RTC crystal oscillator.

Operating Voltage & Logic: Target logic operates at 3.3V DC (with many 5V-tolerant GPIO pins). Powered via USB (5V DC) or through external V_IN power header pins (4.5V to 9V DC).

Handling Precautions: Observe standard electrostatic discharge (ESD) handling safety precautions. Verify proper jumper pin settings (BOOT 0 / BOOT 1) before uploading code via UART or SWD interfaces.

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

Essential 32-Bit Workbench Benchmark: Position as the quintessential entry-level ARM Cortex-M3 development platform for makers, students, and engineers making the jump from 8-bit microcontrollers.

Flexible Software Development Support: Highlight its broad compatibility with popular development tools including STM32CubeIDE, Keil MDK-ARM, and the Arduino IDE framework (STM32duino) for rapid prototyping.

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

Must-Have for Academic & Embedded Workbenches: Ideal cost-effective platform for university microelectronics labs, embedded systems learning, and rapid hardware-in-the-loop prototyping.
