The DesignWare ARC IoT Development Kit is a versatile platform that includes the necessary hardware and software to accelerate software development and debugging of sensor fusion, voice recognition and face detection designs. More information is avaialble here [1] and here [2]. The board is based on real silicon with ARC EM9D-based Data Fusion IP Subsystem. It sports a rich set of I/O including * DW USB OTG * DW MobileStorage (used for micro SD-card) * GPIO * multiple serial interface including DW APB UART * ADC, PWM and eFlash, SRAM and SPI Flash memory * Real-Time Clock (RTC) * Bluetooth module with worldwide regulatory compliance (FCC, IC, CE, ETSI, TELEC) * On-board 9-axis sensor (gyro, accelerometer and compass) Extensible with Arduino, Pmod, mikroBUS connectors and a 2x18 extension header. One of the most interesting features for developers is built-in Digilent USB JTAG probe so only micro-USB cable is needed!
