The 51 microcontroller-specific training board, which is common to many related experimental courses, integrates a small number of peripherals and is designed for the purpose of microcontroller teaching and training. At the same time, it is convenient for students to do graduation projects.
All functional modules are independent, and all pins of the microcontroller are derived. If you need to use the onboard function, you need to connect it with a DuPont cable yourself (including the USB to serial port circuit, you also need to use a jumper to connect to the microcontroller, remember to interleave txd and rxd connections)
