This is start up level 8051 development board with ZIF(Zero Insertion Force) socket for easy inserting and removing microcontroller from board. This board is perfect for programming 8051 microcontroller as well as for designing and testing 8051 based projects.The board has onboard AT89S52 MCU(8K Flash Memory). Board has on board power supply circuit,RS232 port for serial communication with computer and other serial device(GPS modules, GSM Modems,RFID Reader),power status LED(RED),Reset switch, User switch, User LED(GREEN), and port extensions for all 4 ports. ISP (in-circuit programming) header port for easy programming. 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.
