51 development board

The 51 development board is also called the 51 microcontroller experimental board and the 51 microcontroller learning board. It is an experimental and learning device used to learn the 51 model microcontroller. It is a commonly used peripheral of the 51 microcontroller. For example, running lights, digital tubes, matrix keyboards, EEPROM, clocks, buzzers, relays are integrated on a small circuit board. Easy to carry and learn, plug directly into the PC. You can study anytime and anywhere. Some small and medium-sized projects can also be directly developed on this board. After the development is completed, you can redraw the drawings and make boards on this basis, which greatly shortens the company's development cycle and saves hardware costs. .

  Question requirements; 1. The circuit board connection is complete and passes DRC verification; 2. Line width: at least 10mil, and the power line is at least 30mil; 3. The spacing between components and the location of connectors are reasonable; 4. Use prohibited wiring layers to draw the outline ; 5. Reasonable layout, easy for welding; 6. PCB connections have no right angles, fewer holes, and no signs of holes on the microcontroller; 7. Neat and clear, good orthogonality, and not a lot to optimize; 8. Reasonable The traces are routed so that large chunks of copper are continuous without excessive fragmentation.
