With 72MHz clock frequency, 20kb RAM and 64KB flash memory, the processor is better equipped and much more performant than most microcontrollers.
In addition to 27 usable GPIOs, the board offers many features that are rarely supported By most other controllers, such as I2C, SPI, CAN, DMA, USB and Uart.
In contrast to the Chinese comparison products, we have produced our Blue Pill Development Board compatible with STM32 microcontrollers with a modified assembly so that we can easily program the controller via the integrated USB interface.
After playing the boot loader, the controller can be programmed comfortably in the Arduino IDE via the integrated USB interface.
