Wireless RF Modules and dongles for IoT | Coral RF

Product Overview
The N706ZB is a robust, field-proven wireless module designed to deliver reliable, high-power connectivity for dedicated Zigbee and IEEE 802.15.4 networks. It combines the established Texas Instruments CC2538 system-on-chip (SoC)—a dedicated Zigbee/6LoWPAN processor—with the CC2592 range extender to achieve a strong +22 dBm output power. This mature platform offers a stable, cost-optimized solution with substantial 512 kB of Flash memory, making it an excellent choice for upgrading existing designs or developing new, high-performance Zigbee coordinators, routers, and industrial sensors where long-term reliability and network range are paramount.

Key Features & Benefits

✅ Proven High-Power Zigbee Performance: The CC2592 front-end provides +22 dBm of transmit power, significantly extending the range and reliability of Zigbee mesh networks, with a typical line-of-sight range of over 500 meters.
✅ Mature & Stable Platform: Based on the widely adopted CC2538, it offers a stable and well-understood development ecosystem for Zigbee and 6LoWPAN applications, reducing technical risk and accelerating time-to-market.
✅ Ample Memory for Complex Networks: Features 512 kB of Flash, providing ample space for the Zigbee PRO stack, OTA upgrade capability, and substantial application code, supporting full-featured gateways and routers.
✅ Cost-Effective for High-Power Needs: Delivers excellent RF performance at a competitive price point, especially for applications that do not require integrated multi-protocol (BLE/Thread) support from newer chips.
✅ Compact & Integrated Design: All components are integrated on a compact 35 x 18 x 3 mm PCB, which includes a PCB antenna option. All CC2538 I/O and debug pins are accessible for design flexibility.
