8051 Microcontroller Development Board


  1. On-board regulated power supply delivering both 5V and 12V outputs for stable power distribution.
  2. A dedicated serial port for In-System Programming (ISP), facilitating programming and debugging of the microcontroller.
  3. An RS232 serial port, allowing communication with external devices through standard serial connections.
  4. A USB port for ISP and debugging purposes, providing an alternative method for programming and debugging the microcontroller.
  5. A DC power supply connector compatible with both AC and DC inputs (12V), ensuring versatile power source compatibility.
  6. Two interrupt switches providing user interaction for triggering interrupt-based events or functions.


This board is designed to help me learn and improve my skills with EasyEDA software.
