Introduction

The Telegesis ETRX351-LRS and ETRX357-LRS modules are low power 2.4GHz Zigbee modules with an added frontend module (SiGe SE2432L) containing both PA and LNA for highest possible link budget. Based on the latest Ember EM351 and EM357 single chip Zigbee solution the new long-range modules are footprint compatible with the ETRX351 and ETRX357, thus representing a drop-in replacement for all applications where a high link budget is required. 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.
