The Telegesis ETRX351 and ETRX357 modules are low power
2.4GHz ZigBee modules, based on the latest Ember EM351
and EM357 single chip ZigBee
They 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
development the ETRX35x series integrates with ease into
Ember’s InSight development environment.
