Support Arduino programming, see Github https://github.com/stm32duino/Arduino_Core_STM32 for details
 Boards with version V1.3 and above have 3 buttons, reset button, BOOT0 button, and user buttons.
How to enter ISP mode
    Method 1: Press and hold the BOOT0 button and the reset button under the power-on state, then release the reset button, and release the BOOT0 button after 0.5 seconds
    Method 2: Hold down the BOOT0 key when power is off, and release the BOOT0 key 0.5S after power on
    DFU mode: just use the data cable to connect to the computer, if there is a problem of unrecognized, you can properly heat the chip (25 ° C), and then re-enter the ISP mode
    Serial port mode: use USB to serial port to connect PA9 and PA10 of the core board
    Software: STM32CubeProg.
           No need for USB to serial port, no debugger, no computer driver, just a TYPE-C data cable to complete the firmware download
How to enter HID Bootloader after writing to APP
Press and hold the KEY button, click the reset button, LED C13 flashes, release the KEY button to enter

Blue Pill is powered by the powerful 32-bit STM32F103C8T6 ARM processor, clocked at 72MHz. The board operates on 3.3v logic levels but its GPIO pins have been tested to be 5v tolerant. While it does not come with WiFi or Bluetooth like the ESP32 and Arduino variants, it offers 20KB of RAM and 64KB of flash memory which makes it adequate for large projects. It also possesses 37 GPIO pins, 10 of which can be used for Analog sensors since they have ADC enabled, along with others which are enabled for SPI, I2C, CAN, UART, and DMA.The board accommodates two crystal oscillators — one 8MHz crystal and one 32KHz crystal — that can be used to drive an internal RTC (real-time clock). As a result, the MCU can operate in deep sleep mode, making it ideal for battery-powered applications.To program this board, we need to use a simple USB to UART converter, and then we can program it directly via USB from a computer.These boards are very cheap compared to the official Arduino board, and the hardware is open source.

  • Model: STM32F103C8T6.
  • Core: ARM 32 Cortex-M3 CPU.
  • Debug mode: SWD.
  • 72MHz work frequency.
  • 64K flash memory, 20K SRAM.
  • 2.0-3.6V power, I/O.
  • Reset(POR/PDR).
  • 4-16MHz crystal.
  • On-board Mini USB interface, you can give the board power supply and USB communication.
  • Size: 5.3cm x 2.2cm.
