P89V51RD2 Development Board

Introduction

P89V51RD2 Development Board is a low cost development board which have all the basic components needed for gaining a headstart on your first 8051 microcontroller projects. It is made from double sided PTH PCB board to provide extra strength to the connector joints for increased reliability. Board can work on 7 to 15V AC or DC supply. It has built-in reverse polarity protection. 7805 voltage regulator has heat sink for heat dissipation so that it can supply 1Amp current continuously without getting over heated. It has switches for reset and power. It also has RS232 interface with DB9 female connector based on MAX232. All the ports are connected to standard 10 pin FRC connectors. Open pads for connecting microcontroller’s pins to external devices are also provided.It can be programmed using Flash Magic programming utility of NXP’s own programming utility via serial port.
