This board is deal for developing Embedded applications involving Low and High speed Wireless Communication (RF/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. This board can be interfaced with many peripherals like GSM,RFID,DTMF etc.
