Product Attributes

Introduction

This series of modules are low-power 2.4GHz ZigBee modules based on the latest Ember EM351 and EM357 single-chip ZigBee/IEEE802.15.4 solutions. They are designed for integration into any device without requiring RF expertise. By leveraging the EmberZNet ZigBee protocol stack, this series of modules adds powerful wireless networking capabilities to products and accelerates time-to-market. The modules' unique AT-style command line interface enables designers to quickly integrate ZigBee technology without complex software engineering. For custom application development, this series of modules can be seamlessly integrated into Ember's InSight development environment.
