This is an improved version of STM32 blue pill.

STM32F103C8T6 Black Pill Development Board is a low cost but feature rich alternative to an Arduino. The board features an ST Microelectronics STM32F103C8 Arm microprocessor running at a 72MHz clock speed. Coupled with 64K of Flash and 20K of SRAM this development board provides a powerful alternative to an Arduino.

This development board is also not short on peripherals with 30 I/O pins, 14 of which can be configured as 12 bit ADC inputs, 12 as PWM with most pins being 5V tolerant. Supplied with the module are a set of 0.1″ pitch headers (require soldering) which provide the option of breadboard mounting it with easy connection of standard Dupont cables.


  • Uses STM32F103C8T6 chipset
  • Arm Cortex-M3 core
