Introduction

The Telegesis ETRX358x and ETRX358xHR series modules are small outline, low power 2.4GHz ZigBee modules. These 4th 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 ETRX358x series enables you to add powerful wireless networking capability to your products and quickly bring them to market. For custom application development the ETRX358x series integrates with ease into Ember Desktop development environment.

These modules have been designed to be easily integrated into another device and to provide a fast, simple and low cost wireless mesh networking interface. They are based on the ZigBee compliant platform consisting of the single chip family of EM358x SoCs combined with the ZigBee PRO compliant EmberZNet meshing stack. They represent an ideal platform for custom firmware development in conjunction with the ZigBee development kits. No RF experience or expertise is required to add this powerful wireless networking capability to your products. The ETRX358x and ETRX358xHR series of modules offer fast integration opportunities and the shortest possible time to market for your product.

The main building blocks of the ETRX358x and ETRX358xHR modules are the single chip EM358x SoC, a 24MHz reference crystal and RF front-end circuitry optimized for best RF performance. The modules are available with on-board antenna or alternatively a U.FL coaxial connector for attaching external antennae. Modules with the U.FL connector are identified by the “HR” suffix. The integrated antenna is an Antenova Rufa. The ETRX358x and ETRX358xHR are used for ZigBee applications.
