ZigBit Module with Balanced RF Output is a low-power, best-in-class sensitivity 802.15.4 / ZigBee module. In just under half a square inch of space comes an impressive set of features you will be hard pressed to find anywhere else. Based on a solid combination of the popular ATmega 1281v MCU and the latest Atmel AT86RF230 radio transceiver, this ZigBit version offers superior radio performance and is ideal for price-sensitive applications.
ZigBit Module with Balanced RF Output minimizes bill of materials (BOM) and shortens time to market, while embedded 802.15.4 / ZigBee software ensures standards-based wireless connectivity for a wide range of applications.
ZigBit Module Hardware Platform
ZigBit is based on the innovative Atmel 802.15.4 hardware platform. The powerful ATmega 1281v MCU features 128kb of flash memory and 8Kb of RAM. The AT86RF230 transceiver offers -101dBm of Rx sensitivity and up to +3dBm of Tx power. This combination, called the "link budget" is related to its range of operation. The difference in link budget – just 9dBm – nearly triples its range. Thanks to the outperforming link budget, the range of AT86RF230 is 2.8 times that of its competitors.
