Universal Board

Universal Board supports 3 different Micro controllers i.e., 8051,PIC and AVR . This board is powered by USB port and does not need external power supply. An extra adapter socket is also provided for Power Supply(9v). It is ideal for developing Embedded applications involving High speed Wireless Communication (Zigbee / Bluetooth ), Real Time Data Monitoring and Control, Interactive Control Panels etc. On Board ICSP Circuits and Serial Port Programmer eliminates need of an additional programmer and allows on board programming. DIP switches are provided for selecting any one of the 3 controller modes.
Note: Only one DIP switch should be turned On at any point of time which corresponds to the Micro controller used.
