Product Overview The N705BS is a highly integrated, cost-effective wireless module designed for IoT applications that require a balance of good performance, extended range, and simplified system design. It is centered on the Texas Instruments CC2652P wireless microcontroller, which integrates a +20 dBm power amplifier (PA) directly on-chip, eliminating the need for external RF components and reducing overall BOM cost. Supporting key protocols such as Zigbee, Bluetooth® 5.2/5.3 Low Energy, and Thread, the N705BS provides a reliable, ready-to-integrate wireless solution for smart home routers, commercial sensors, and other connected devices where value and reliability are paramount.
Key Features & Benefits
✅ Integrated Power Amplifier for Simplified Design: The on-chip +20 dBm PA delivers reliable, extended-range communication (up to 400 meters) without the complexity and cost of an external RF front-end, streamlining the development process.
✅ Comprehensive Multi-Protocol Support: Offers firmware-level support for Zigbee, Bluetooth 5.2/5.3 LE, Thread, and IEEE 802.15.4, providing flexibility to adapt to various market ecosystems and application requirements.
✅ Cost-Optimized Performance: Based on the power-efficient CC2652P platform, it delivers a compelling feature set—including 352 kB of Flash and 80 kB SRAM—at an attractive price point for volume applications.
✅ Compact and Complete: All necessary components are integrated onto a tiny 35 x 18 x 3 mm PCB. All CC2652P GPIOs and debug pins are accessible, offering full design flexibility for peripheral integration and firmware development.
✅ Reliable Operation: Designed to operate across a -30°C to +80°C temperature range, ensuring stable performance in typical indoor and commercial environments.
