OpenH743I-C Standard, STM32H7 Development Board

OpenH743I-C is an STM32 development board designed for the STM32H743IIT6 microcontroller, consists of the mother board and the MCU core board CoreH743I.

The OpenH743I-C supports further expansion with various optional accessory boards for specific application. The modular and open design makes it the ideal for starting application development with STM32 series microcontrollers.

User Manual

Onboard Peripherals

1. MCU core board connector: for easily connecting the CoreH743I
2. Arduino interface: for connecting Arduino shields
3. DCMI interface: for connecting camera
4. 8-bit FMC interface: easily connects to peripherals such as NandFlash
5. ULPI interface: for connecting high-speed USB peripheral (the STM32H743I integrates USB HS controller without any PHY device)
6. LCD interface 1: for connecting 10.1inch LCD, 7inch LCD, 4.3inch LCD
7. LCD interface 2: for connecting 4.3inch LCD
8. SAI1 interface: for connecting audio modules
9. ICSP interface: Arduino ICSP
10. SPI interfaces:
    • easily connects to SPI peripherals such as DataFlash (AT45DBxx, W25QXX), SD card, MP3 module, etc.
    • easily connects to AD/DA modules (SPI1 features AD/DA alternative function)
11. Ethernet interface: for connecting Ethernet modules
12. I2S / I2C interface: easily connects to I2S peripherals such as audio module, etc.
13. USART1 connector: USB to UASRT via the onboard convertor CP2102 
14. QUADSPI interface: 4-wires SPI interface (the H7 series latest peripheral interface), for connecting serial Flash modules like W25QXX Board
15. SDMMC interface: for connecting Micro SD module, features much faster access speed rather than SPI
16. USART3 interface: easily connects to RS232, RS485, USB TO 232, etc.
17. CAN2 interface: for connecting CAN modules
18. CAN1 interface: for connecting CAN modules
19. I2C1/I2C4 interface: easily connects to I2C peripherals such as I/O expander (PCF8574), EEPROM (AT24Cxx), 10 DOF IMU Sensor, etc.
20. MCU pins connector: all the MCU I/O ports are accessible on expansion connectors for further expansion
21. 5V DC jack
22. 5V/3.3V power input/output: usually used as power output, also common-grounding with other user board
23. Power supply switch: powered from 5VDC OR USB connection of the USART1
24. CP2102: USB to UART convertor
25. LEDs: convenient for indicating I/O status and/or program running state
26. Joystick: five positions
27. WAKE UP button: used as regular button, and/or wake up the STM32 MCU from sleep
28. Reset button
29. USART1 jumper
30. LED jumper
    • short the jumper to connect to default I/Os used in example code
    • open the jumper to connect to custom I/Os via jumper wires
31. KEY jumper
    • short the jumper to connect to default I/Os used in example code
    • open the jumper to connect to custom I/Os via jumper wires
32. Arduino jumper
    • short the upper pins, A4, A5 is used as AD function
    • short the lower pins, A4, A5 is used as I2C function
