ZEBRA StarterkitZEBRA (ZigBee Enabled Board for Radio Applications) is a radio module for wireless connectivity, sensor networks, IEEE 802.15.4 and ZigBee. The module is based on the ZRP-1 chip set of Freescale Semiconductor, works in the 2,4 GHz ISM band and enables wireless connections with a distance of 10 to 30 meters in buildings.

The shielded module has dimensions of only 16 x 33 mm and contains the baseband processor, the RF-IC and a chip antenna. Therfore, nothing else than the supply voltage is required to start working. The module is equiped with a 50-Pin HIROSE receptacle and can be integrated in embedded applications. Alternatively, a version with a BGA SMT footprint is available.
