Description: 

The 8051 Quick stater development board is suitable for programming 8051 microcontroller(Required external ISP programmer for AT89S52) from Atmel as well as for designing and testing 8051 projects. This board contains on board device such as alphanumeric 16x2 LCD display,DS1307 RTC, port expander,power supply circuit,RS232 port for serial communication,power status LED(RED),Reset switch, User switch, User LED(GREEN),etc,that conveniently interface with 8051 microcontroller and allow you to easily simulate the operation of target device.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 connection without an external programmer.
