Introduction to STM32F407 Discovery Kit 3


As an Embedded enthusiastic, If you are interested in twiddling with libraries and internal registers of microcontroller, the STM family is great to start with as they provide a wide range of ready to use libraries and IDEs. STM family have several microcontrollers boards, but fortunately, beginners functions are available in all. In this article, we are going to learn about the STM32F407 discovery board.


  1. The core unit consists of Arm® Cortex®-M4 32-bit processor.
  2. Supports FPU and DSP instructions for high speed.
  3. Have 100-pin LQFP package.
  4. Uses ST-LINK/V2 embedded debug tool for programming and debugging.
  5. Built-in 3-axis accelerometer and Omni-directional digital microphone.
  6. Built-in audio DAC along with class D type speaker driver.
  7. Consist of a total of 8 LEDs, of which 4 are User LEDs.
  8. Consist of user and reset push-buttons.
  9. Support wide range of IDEs
  10. Flexible power supply options.
  11. Core operates at a frequency of 168MHz
  12. Seven channel matrix AHB bus for fast switching.
  13. Support I2C. SPI, as well as UART modes for communication.
  14. Low power operation.


As the below image depicted, the board consist of Power LED, Audio jack, Micro USB port, SWD (Serial Wire Debug), Mini USB ST-Link debugger, User and Reset buttons, Header pins, Crystal oscillator and four user LEDs (Red, Orange, Blue and Green) etc. The board consists of headers pins connected to the Five ports of the core, i.e. A, B, C, D and E.

Firstly establish a connection between board and computer using a  This cable is connected through a USB connector CN1 on the board. The four user LEDs starts blinking in one by one manner. STM32 DISC board have preloaded program for MEMS sensor. As you press the user button on the board, the sensor will enable.When you tilt or move the board, the LEDs represents the direction and speed of movement.


STM32 Discovery Board is compatible with several IDEs so that you can choose according to your convenience. Here I have mentioned the list of IDEs that are compatible with the STM Boards.

I have used an Atolic Truestudio for programming the board, as it is easy to install libraries and simple to use. Make sure to install STM32 ST-LINK Utility on your device before uploading the code. Procedure and guidelines for creating a project, uploading code, and debugging vary as per the IDE.

As you can see above GIF, I have uploaded a basic interrupt program in a Board. All four LEDs remains ON until the interrupt is introduced. This interrupt can be introduced using the Reset button on the board.

Final Thoughts:

I hope now you are familiar with the STM32F07 Discovery Board. Learning and working on STM boards requires Patience, Interest and Consistency.  If you have any thoughts regarding it, please let us know in the comment section.
