51 microcontroller DIY development board (97% direct plug-in)

51 single-chip computer DIY development board (97% direct plug-in)
1. Introduction to the development board
       51 single-chip microcomputer development board, the required components except CH340 are all in direct plug-in packaging, which is easy to weld. The development board includes resources such as LED, digital tube, buttons, DS18B20, AT24C02, DS1302, passive buzzer, infrared receiver, ADC*DAC module, etc., which can meet the basic microcontroller teaching requirements.
