ETRX2 ZigBee Module

Exceptional ZigBee functionality without the need for specialist skills
The Telegesis ETRX2 module is a low power, 2.4GHz ISM band transceiver, based on the Ember EM250 single chip ZigBee / IEEE802.15.4 solution. It has been designed to be integrated into any device without the need for RF experience and expertise. Utilizing EmberZNet2.2 meshing technology, the ETRX2 enables you to add powerful wireless networking capability to your products and quickly bring them to market. The module's unique AT-style command line interface allows you to quickly integrate meshing radio technology without complex software engineering.

Radio Features

• Based on the Ember EM250 single chip ZigBee / IEEE802.15.4 solution
• 2.4GHz ISM Band
• 250kbit/s over the air data rate
• 16 channels (802.15.4 Channel 11 to 26)
• +3dBm output power ( +5dBm in boost mode)
• High sensitivity of -98dBm typ. At 1% packet error rate
