STM32F407VET6 core board design

1. Function description

• STM32F407VET6 microcontroller core board, used for learning and functional verification.

2. Design features

• 2kb EEPROM
• RepRap 12860 Monitor Interface
• Freely switchable BOOT circuit design
• A test LED light

3. Other instructions

The schematic diagram refers to the designs of many developers at home and abroad.

• Puzhong F407ZGT6 development board schematic diagram
• F407VET core board schematic of WeAct studio
• Waveshare's F407VET6 core board open source schematic diagram
• I also referred to ST’s official data manual and the schematic diagram of a Taobao store (can’t remember which one)

There is basically no problem with the schematic diagram. However, due to the author's lack of PCB wiring experience, there may be some defects in this aspect. I hope that seniors can improve it.

4. Engineering Bug Records

20200728—BUG—The pin spacing is wrong—2.54 pins cannot be soldered—Unmodified 20200728—BUG—The emulator cannot recognize the ST chip—Solution: Hold both sides of the board and lift the board off the table to identify the chip. download.

5. Project progress

20200728: The board has been soldered and the minimum system is operating normally. The test code is initialized using STM32CubeMX. I simply wrote a test program for flipping the level status of a small light. The download test run was successful. The test video and code will be uploaded later. Other functions have not been tested yet. In addition, I found a problem during welding. The spacing of the pin headers is not 2.54mm . I will modify it in the next version.
