- Detail
- Parameters
N517BS-B: 1.2Watt (+31dBm) Long-Range 868/915Mhz FSK Transceiver Module
Product Overview
The N517BS-B is a high-performance, +31dBm narrowband FSK transceiver module designed for long-range IoT and M2M communication. Based on the Texas Instruments CC1125 chipset and integrated with skyworks FEM, it delivers outstanding -126dBm receiver sensitivity and a line-of-sight range of over 15.5 km. This compact, SPI-controlled module is a complete RF solution supporting 868 MHz and 915 MHz ISM bands, ideal for smart metering (AMI), industrial telemetry, and wide-area sensor networks.
Key Features & Benefits
High Power & Superior Sensitivity: Combines +31dBm (1.2 Watt) output power with -126dBm sensitivity at 1.2kbps to ensure robust links in challenging environments.
ISM Band Support: Pre-configured variants for worldwide deployment: 868MHz (EU), and 915MHz (USA).
Exceptional Range: Engineered for maximum distance, achieving >15.5 km LOS range (at 1.2kbps with a 3dBi antenna).
Compact & Complete Design: All core electronics are integrated onto a tiny 29.5x21x3 mm PCB, superior thermal management, simplifying your design-in process.
Standard SPI Interface & Full Pinout: Easy host microcontroller integration via SPI, with all CC1125 pins accessible for advanced customization.
Industrial Reliability: Operates reliably across an extended temperature range for harsh outdoor and industrial applications.
