Well now it has all the components anybody would ever need to learn every aspect of coding on this platform, really! It is a very simple and yet uses almost every pin/feature of the 8051. It is very cheap to build and covers the whole development life cycle of the controller just like for a production circuit, because you need to take out the chip and burn the new firmware then put it in again.

Features:

  • 40-pin DIP controller 8052 or similar – ATmel being used here
  • 12 MHz crystal
  • Reset
  • Buzzer
  • LEDs on one port
  • DIP switches on one port controlling the LEDs
  • 5V regulator (can be powered by a 9V standard battery)
  • 2 digit 7-segment display
  • 2 push buttons, one to increment and one to decrement the number displayed
  • RS-232 serial port can update numeric display and buzzer frequency, also send data of dip and push buttons to PC
  • A simple PC application can show status of all connected peripherals

everything possible demo on an 8051
