SILICON LABS ETRX357-R8

The Telegesis ETRX351 and ETRX357 modules are low power 2.4GHz Zigbee modules. These 3rd generation modules have been designed to be integrated into any device without the need for RF experience and expertise. Utilizing the EmberZNet Zigbee stack, the ETRX35x 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 ETRX35x series integrates with ease into Ember’s InSight development environment.
