Note: Pre-soldered Header Pin

This is the famous Arduino compatible board that based on STM32F103C8T6 ARM Microcontroller. STM32F103C8T6 is ARM Cortex-M3 core from STMicrcoelectronics. This board is often called the Blue Pill (Matrix reference). Of course with the 32-bit ARM CPU, it can easily beat Arduino UNO in performance. As an added bonus, you can easily program this board using your Arduino IDE.

With the pre-soldered header pin, you can start using this powerful Arduino compatible board out of the box :)

BTW, you might need a USB microB cable to power this board and USB to Serial (UART) Converter to load program. For example, this is a guide from maker.pro:

In case you like to watch video, here is another guide from Joop Brokking:


  • MCU: STM32F103C8T6
  • Core: Single Core, Arm Cortex-M3
  • Operating Voltage: 3.3VDC
  • Max. Clock Speed: 72MHz
  • FLASH: 64KB
  • SRAM: 20KB
  • HSI: 8MHz
  • LSI: 40KHz
  • HSE: 8MHz
  • LSE: 32.768kHz
  • GPIO Pins – 32 with external interrupt capability
  • Timers – 3 16-bit Timers, 1 16-bit PWM Timer
  • PWM Pins – 15
  • Analog – 10 Channels of 12-bit ADC
  • I2C – 2 I2C Peripherals
  • USART – 3 USART Peripherals with hardware control
  • SPI – 2 SPI Peripherals
  • Other Peripherals – USB 2.0 Full Speed, CAN 2.0B
  • Power Sources
    • Any +3.3V pin (+3.3V)
    • Any +5V pin (+5V)
    • USB connector (+5V)
  • PCB Size:  (w x l)23mm x 53mm

Note: The +5V pins on this board are directly connected to the +5V pin of the USB connector. There is no protection in place. Do not power this board through USB and an external power supply at the same time.

Note: This board may have a wrong value of resistor on the USB D+ pin. Instead of a 1.5kΩ, it has either a 10kΩ or 4.7kΩ resistor. This can be solved by replacing the resistor with the right value.

Packing List:

  • 1 x STM32F103C8T6 Blue Pill Pre-soldered header
