Pin Connections & Pinout

The Blue Pill exposes the STM32F103C8T6's GPIO, power and communication connections along both sides of the PCB. Pin labels are printed directly on the board.

The exposed connections can be configured for functions including:

• Digital GPIO
• Analog inputs
• PWM
• I2C
• SPI
• USART
• Timer functions
• Power and ground

A dedicated SWD header is provided for programming and debugging, while BOOT0 and BOOT1 jumpers allow the boot configuration to be selected.

Individual GPIO numbers and alternate-function mappings are intentionally not repeated here because STM32 pins can support multiple alternate functions depending on firmware configuration.

Programming & Development

The board can be used with common STM32 development environments and programming workflows, including:

• STM32CubeIDE
• STM32CubeMX
• Keil MDK
• PlatformIO
• Arduino IDE with compatible STM32 core
• ST-LINK programming/debugging

For development and debugging, SWD is particularly useful with an ST-LINK programmer/debugger.

The STM32F103 family officially supports SWD and JTAG debugging at the MCU level.

Communication Interfaces

The STM32F103C8 MCU provides multiple communication peripherals for connecting external hardware:

I2C — useful for compatible sensors, displays and peripheral ICs.

SPI — suitable for displays, memory devices, sensors and high-speed peripherals.

USART — provides serial communication with modules and other controllers.
