N515BS-B CC1125 High-Power Narrowband RF Module
Product Core
A professional-grade, ultra-long-range narrowband RF module based on the TI CC1125 transceiver and integrated with external PA & LNA. It operates on 169/433/868/915MHz bands, delivering +25dBm (300mW) output power and -126dBm sensitivity, engineered for reliable communication over distances exceeding 12 kilometers in industrial telemetry and remote control applications.
Key Features
📡 Extreme Power & Range: +25dBm (300mW) output power enables robust, long-distance links over 12,000+ meters in line-of-sight conditions.
🎯 Superior Narrowband Performance: -126dBm sensitivity and support for channel spacing down to 1 kHz ensure excellent interference immunity and spectral efficiency for telemetry and SCADA.
🌍 Global Band Support: A single hardware platform supports major global Sub-1GHz ISM bands: 169, 433, 868, and 915 MHz.
🔋 Industrial Durability: Operates in extreme temperatures from -40°C to +85°C, built for harsh outdoor and industrial environments.
🛠️ Full Developer Control: All CC1125 pins are accessible via a standard SPI interface for complete custom firmware and protocol development.
