#The 5th Lichuang Electronic Design Competition#32-bit MCU motherboard

Note: * is a required field.

[Please fill in during the registration stage↓]
* 1. Self/Team Introduction
This project is designed by an individual.
* 2. Briefly introduce the project
This project is to design a low-cost, stable (can be changed to module use).

[Please fill in during the competition stage↓]
* 1. Describe the project details
1. The stm32F107 used here can also use GDstm32F107, which is compatible.
2. Dual CAN. TI chips are used here. Domestic chips can be compatible here.
3. Dual current detection: up to 310V DC.
4. 10~100M Ethernet interface.
5. Several basic buttons and several indicator lights required for debugging.
6. A high-speed USB interface.
* 2. Describe the challenges faced by the project and the problems solved.
Solve the problem that beginners buy development boards that are expensive, unstable, and do not meet the requirements.
* 3. Describe the key points involved in the hardware and software parts of the project
1. Solid copper,
2. Slots are made to leave enough safety spacing.
3. The Ethernet routing is close enough.
4.USB static protection is on the outermost side, try to keep static electricity at the input port.
 This USB can be hot-swapped.
* 4. Project material list display
![1.png] Supplementary note: The pin. button, can, and current detection materials used in the bom can be replaced and adjusted according to your needs.
* 5. Project picture upload
          5.1. Print the competition logo picture on the PCB. If you ignore it, it will be regarded as giving up the competition .
          5.2. Other pictures of the project
![QQ screenshot 20200918183547.png] ![QQ screenshot 20200918183631.png] ![1600596511780.jpg] ![1600596511773.jpg] There is a line in the picture that was originally left to connect to the ground, but it was not connected because the spacing was not enough. The pad was reinforced.
* 6. Demonstrate your project and upload it as a video.
          6.1. Upload the video to the official website of the competition.
          6.2. Video title and link at Bilibili

. Notes: ①: Video requirements: Please shoot in horizontal mode, with a resolution of no less than 1280×720, in Mp4/Mov format, and a single video size limited to 100M; ②: Video upload: Please upload it to the official website of the competition and Bilibili ([www.bilibili.com](www.bilibili.com)) at the same time. The top 10 projects on Bilibili will receive a cash reward of RMB 1,000-5,000, and other uploaded projects will receive a RMB 100 coupon for the EasyChuang Mall; ③: Video title: The 5th EasyChuang Electronic Design Competition: {Project Name}-{Video Module Name}; such as the 5th EasyChuang Electronic Design Competition: "Autonomous Driving" project-Team Introduction. < /span>< /span>< br>

* 7. Is it the first public release?
          7.1. Has the project been published or won awards before? Please indicate that
this project has not been published before.
          7.2. If the project is optimized on the original basis, please indicate
the addition of WiFi module in the optimized part. If you want to reduce the difficulty of drawing board, you can increase the number of layers. Use 0603 package or 0402 resistor to shorten the routing of Ethernet and microcontroller.
