ZigBee/802.15.4 Application Kit from Rabbit Semiconductor and MaxStream

Rabbit Semiconductor and MaxStream offer solution for ZigBee wireless control system developer. The ZigBee/802.15.4 Application Kit combines MaxStream XBee RF modem with the popular RCM3720 RabbitCore module. ZigBee paired with the RCM3720 provides a low-cost, robust wireless infrastructure that allows users to monitor and control remotedevices within a wireless meshed network.

ZigBee, based on the established IEEE 802.15.4 standard for packet-based, is a wireless technology known for its reliable, low-cost, lower power characteristics.

The kit contains three MaxStream® 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.

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 kit serves as a template for countless wireless applications where low power and low data rates are required. The samples illustrate how a user can connect via the various topologies such as point-to-point, point-to-multipoint, and mesh.
