STM32H750 core board

Open source 32 main control board in the laboratory (the function is still in the testing stage)

Currently covered:

1. F103VBT6

2. F407VGT6

3.H750VBT6

The onboard resources of the three models are similar, and the BTB base pin sequence is the same. Common functions can be achieved under the same pin design.

Onboard resources:

1. 3 WS2812 RGB and 2 LEDs, 1 buzzer and 1 three-way toggle button

2. spi’s FLASH chip and IIC’s EEPROM chip

3. 5V->3.3V step-down circuit

4. USB-C power supply and CH340 serial port conversion

5. OLED LCD display device (F1 and F4 are 12832 OLED, which will be updated to 12864 OLED with font later, and H750 is a 16080 color screen with font)

6. MPU6050 gyroscope (F1 and F4 circuits are not perfect, H750 is to be tested)

7. The serial port is led out with 3 SH1.0 interfaces (4 for H7), the 4-wire STLINK download is led out, and the IO port except the buttons is led out with two 41Pin BTB sockets.

Follow-up plan:

1. Test all onboard functions

2. A variety of supporting complete work plans are open source

3. Other models supported

Also note:

1. If you need to make your own board, please use the included AD software to draw the PCB. I am not proficient in Lichuang EDA.

2. If you want to implement specific application functions and need to use it with a base plate, it is recommended to design a base plate with specific functions yourself to improve the user experience.
