STM32F103C6T6 Blue Pill ARM Cortex-M3 Dev Board

STM32F103C6T6 Blue Pill – ARM Cortex-M3 Development Board

The STM32F103C6T6 “Blue Pill” is a compact, low-cost ARM Cortex-M3 development board that offers significantly more processing power and peripheral richness than typical 8-bit Arduino boards. Running at up to 72 MHz with a 32-bit architecture, it is a popular upgrade path for makers and engineers who need more performance in a small form factor.

Key Specifications

• MCU: STM32F103C6T6 (ARM Cortex-M3)
• CPU Speed: Up to 72 MHz
• Flash: 32 KB
• RAM: 10 KB SRAM
• GPIO: 37 I/O pins
• Interfaces: 2× SPI, 2× I2C, 3× USART, USB 2.0 Full Speed, CAN
• ADC: 2× 12-bit ADC (10 channels)
• Operating Voltage: 3.3V logic, 5V tolerant pins
• Programming: ST-Link/V2 via SWD, or USB DFU bootloader

Compatibility & Use Cases

Programmable via Arduino IDE (STM32duino core), STM32CubeIDE, and PlatformIO. Compatible with most Arduino libraries via the STM32 HAL abstraction. Common applications include:

• High-speed data acquisition and signal processing
• USB HID and CDC device development
• CAN bus and industrial protocol interfaces
• Motor control and servo driver projects
• IoT gateway and edge processing nodes

Requires an ST-Link/V2 programmer for initial flashing or use the USB DFU bootloader for cable-only programming.
