ZigBee™/802.15.4 Application Kit

The ZigBee/802.15.4 Application Kit combines Digi’s XBee™ RF modem with the popular RCM3720 RabbitCore™ module along with an easy-to-use interface to help customers build a practical ZigBee wireless control network. ZigBee paired with the RCM3720 provides a low-cost, robust wireless infrastructure that allows users to monitor and control remote devices within a wireless meshed network.

ZigBee is a wireless technology known for its reliable, low-cost, lower power characteristics, based on the established IEEE 802.15.4 standard for packet-based, wireless data transport. Rabbit®’s ZigBee/802.15.4 Application Kit provides all the tools to integrate a ZigBee wireless module into your Rabbit-based solutions.

The kit contains three Digi® ZigBee modules for full application reference. One ZigBee module is connected to an Ethernet enabled RCM3720 RabbitCore Module. The RCM3720 runs at 22.1 MHz, and provides 10Base-T Ethernet, 512K Flash, 256K SRAM, 1MB Serial Flash as on-board memory, and 33 GPIO lines. The other two ZigBee modules are standalone node devices.

Samples, libraries and firmware helps to integrate a ZigBee network into a Rabbit-based embedded solution. A user-configurable interface allows users to set up a network, discover other similar ZigBee devices, and control LEDs and switches from an RF Interface board as a node device. The samples illustrate how a user can connect via the various topologies such as point-to-point, point-to-multipoint, and mesh. The kit serves as a template for countless wireless applications where low power and low data rates are required.
