Hi friends.I need a 8051 Development Board Circuit diagram especially 89020 one.I have this Board because of a workshop.
I need this circuit to advance its use.This board is
Compatible with most of the 8051 and 8052 series of microcontroller
Available with AT89s51, AT89s52 or P89v51RD2 microcontroller
On board motor driver for driving 4 DC motors or 2 stepper motors
LCD interface
PC interface through UART
8 channel ADC converter
11.0592 MHz crystal
Exposed 8 channel 3 I/O port for general-purpose application
Five tact switches for external input, reset and interrupt
Four test LEDs for status and debugging purpose
Exposed ISP pins for Programming
Programming can be done through serial port for P89v51rd2 micro controller
On board regulated power supply

Please reply

I think you can make this on your own if you know all this. And most probably the vendor should have provided circuit with the dev board otherwise its of no use.

Can u tell me whether this is a general board whose circuit may be available on net?
