ETRX2HR is an Telegesis wireless mesh networking module with ember ZigBee technology with hirose U.FL antenna connector. These modules are a low power 2.4GHz ISM band transceiver, based upon the Ember EM250 single chip ZigBee / IEEE802.15.4 solution and EmberZNet 2.xx meshing technology. Designed for integration into any device without the need for RF expertise the ETRX2 enables the user to add powerful wireless networking capability to their products and bring them quickly to market. The ETRX2-PA offers boosted output power whilst being a drop in replacement for the standard ETRX2. Care was taken to retain the low deep sleep current to make this module ideally suited for battery operated end devices with the lowest transmit current in its class.
