CT-EM250 ZigBee-Ready RF Transceiver Modules

Introduction

The CT-EM250 series of modules are specially designed for ZigBee application. They

provide a fast jump start design for system integrators or electronic designers wishing

to use ZigBee wireless technologies. The module contains qualified RF hardware and

enough processor power to run the EmberZNet stack or other ZigBee network stack

(depending on version), making it a powerful platform for building wireless networking

products. ZigBee Coordinators (ZC), ZigBee Routers (ZR), and ZigBee End Devices

(ZED) are all supported and are programmed onto the module together with a custom

application. Minimal RF design experience is need to use CT-EM250 modules.
