LPC2148(ARM7) Development Board

LPC2148 Development Board is a powerful development platform based on ARM7TDMI microprocessor. This board is powered by USB port and does not need external power supply. It is ideal for developing Embedded applications involving High speed Wireless Communication (Zigbee / Bluetooth ), Real Time Data Monitoring and Control, Interactive Control Panels etc. The UART boot loader eliminates need of an additional programmer and allows you to program using serial port. The board is made from double sided PCB board to provide extra strength to the connector joints for increased reliability.
