STM32F103C8T6 ARM Cortex-M3 Minimum System Core Board

The STM32F103C8T6 ARM Cortex-M3 Minimum System Core Board is a high-performance, ultra-compact development board designed for demanding embedded applications. Powered by a 32-bit ARM Cortex-M3 RISC core operating at a high-speed 72 MHz frequency, this board offers significantly more processing power, memory, and peripheral options than standard 8-bit microcontrollers. Its miniature, square form factor makes it an exceptional choice for space-constrained projects, custom flight controllers, smart wearables, and battery-powered systems.

This core board features an onboard Micro-USB connector for power and basic communication, a dedicated reset button, and dual-row header pins that break out all essential I/Os for easy integration into custom PCBs or breadboards. It is fully compatible with popular development environments including Arduino IDE (via STM32duino), Keil MDK, and STM32CubeIDE. Programming and debugging are made seamless using the onboard Serial Wire Debug (SWD) interface connected to an ST-Link V2 programmer.

Features:

• High-Performance Core: Powered by the 32-bit ARM Cortex-M3 processor running at up to 72 MHz.
• Generous Memory: Equipped with 64 KB of Flash memory and 20 KB of SRAM for complex application code.
• Ultra-Compact Design: Square, space-saving layout ideal for miniature drones, flight controllers, and portable IoT nodes.
• Onboard USB Interface: Features a Micro-USB port for convenient power input and USB communication.
• Dual-Row Pin Headers: High-density pin layout breaks out GPIOs, SPI, I2C, USART, and ADC channels.
• Onboard Crystals: Includes an 8 MHz system crystal and a low-power 32.768 kHz RTC crystal.
• Easy Debugging: Dedicated SWD interface for rapid programming and real-time debugging with ST-Link.
