The N530DS is a family of versatile, ultra-low-power Sub-1GHz wireless communication modules built around the powerful and efficient Texas Instruments CC1311R3 system-on-chip. Designed for global IoT deployments, the series offers variants targeting specific ISM frequency bands, including the less congested 169MHz band as well as the popular 433MHz, 868MHz, and 915MHz bands. These modules combine exceptional RF performance, years of battery life, and a flexible interface in a compact surface-mount package, making them an ideal connectivity solution for smart metering, home automation, industrial sensing, and medium-to-long-range data links.
Key Features & Benefits
Multi-Band Flexibility: Choose from models optimized for 169MHz (EU/China) operations, enabling global deployment.
Exceptional Power Efficiency: Features a deep sleep current as low as 0.7 µA, enabling multi-year operation on battery power for duty-cycled applications.
Long Range & Robust Link: With up to +14 dBm output power and a superb receiver sensitivity of -121 dBm, reliable communication over distances exceeding 1500 meters is achievable.
Developer-Centric Design: Full pin-out access to the CC1311R3 MCU allows for extensive secondary development and peripheral integration.
Rapid Integration: Built-in AT command set via UART interface significantly reduces protocol development time and simplifies host processor integration.
Compact & Cost-Effective: The N531CS variant emphasizes a low-cost, small-footprint design without compromising core functionality, perfect for high-volume applications.
