The ETRX357 module is a low power 2.4GHz ZigBee module, based on the latest Ember EM357 single chip ZigBeeTM / IEEE802.15.4 solution. It is designed to be integrated into any device without the need for RF experience and expertise. Utilizing the EmberZNet ZigBee stack, the ETRX357 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 designers to quickly integrate ZigBee technology without complex software engineering. For custom application development the ETRX357 series integrates with ease into Embers InSight development environment.
