STM32 development board designed for the STM32F407IGT6 MCU, and integrates various standard interfaces, pretty easy for peripheral expansions.


Open407I-C is an STM32 development board designed for the STM32F407IGT6 microcontroller, consists of the mother board and the MCU core boardCore407I.

The Open407I-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 STM32F4 series microcontrollers.

  18. ONE-WIRE interface: easily connects to ONE-WIRE devices (TO-92 package), such as temperature sensor (DS18B20), electronic registration number (DS2401), etc.
  19. 5V DC jack
  20. 5V/3.3 V power input/output: usually used as power output, also common-grounding with other user board
  21. MCU pins connector: all the I/O ports are accessible on expansion connectors for further expansion
  22. 74LVC139: used for FSMC expansion, make it possible to connect multi devices through FSMC at the same time, such as LCD and NAND FLASH
  23. LEDs: convenient for indicating I/O status and/or program running state
  24. User key: convenient for I/O input and/or interact with running code
  25. Wake-Up button: wake up the STM32 MCU from sleep mode, also used as regular user key
  26. Joystick: five positions
  27. Crystal empty slot (on bottom side): for soldering 50M active crystal oscillator, which'll provide clock to DCMI
  28. 74LVC139 selection jumper: for FSMC chip select
  29. PS/2 jumper
  30. LEDs jumper
  31. User key / joystick jumper

For jumpers 27-30:

  • short the jumper to connect to I/Os used in example code
  • open the jumper to connect to other custom pins via jumper wires
