Module Overview
2.1 Overview
ZigBit is a low-power, high-sensitivity IEEE 802.15.4/ ZigBee-compliant OEM module. This multi-func-
tional device occupies less than a square inch of space, which is comparable to a typical size of a single
chip. Based on a solid combination of Atmel’s latest MCU Wireless hardware platform [1], the ZigBit
offers superior radio performance, ultra-low power consumption, and exceptional ease of integration.
