The document describes a Zigbee evaluation board that interfaces with an ARM7 microcontroller. It allows for low-power wireless communication using the IEEE 802.15.4 networking protocol at distances up to 1 mile line-of-sight. The board features an XBee or XBee Pro module, peripherals for analog input and output, and interfaces to connect to a host PC or embedded device via an RS232 connection. It can be used to transfer data and files wirelessly between nodes and interface with an ARM7 development board for wireless sensor and control applications.
