40 pin 8051 Evaluation Board

40 pin 8051 Basic Development Board - USB

Availability: In stock

A general purpose 40 pin 8051 development board with onboard USB support, power supply circuit, RS232 port for serial interface with computer and other serial devices, reset switch, power status LED and a general purpose switch and LED.

The board features an onboard USB to Serial converter which can be used to program the microcontroller and do serial communication between the microcontroller and the computer over the USB port. This greatly increases the easy with which the board can connect and communicate with computers. The board is compatible with the AT89S51/52 and the P89V51RD2 microcontrollers. The P89V51RD2 allows serial programming and can be programmed directly with this board through a serial or USB connection without the need for an additional external programmer.

This board is perfect if you are just starting out with 8051 programming and also if you want a reliable tried and tested board for building advanced projects based on it.
