N531DS 169MHz Wireless Module

TI CC1311R3-Based | Ultra-Low-Power | Long-RangeOverviewThe N531DS is a specialized, ultra-low-power wireless module designed for the 169MHz ISM band. Based on the Texas Instruments CC1311R3 system-onchip, it provides exceptional range and years of battery life, making it ideal for critical infrastructure and utility applications like smart metering across the EU and China.

Key Features

• Dedicated 169MHz Band: Optimized for reliable, long-range communication in the 169-170 MHz spectrum.

• Ultra-Low Power: Sleep current as low as 0.7 µA enables multi-year battery operation.

• Long Range & Robust: +14 dBm output power and -121 dBm sensitivity ensure stable links over distances up to 1500m.

• Easy Integration: Built-in AT command set via UART for rapid development and host MCU control.

• Full Development Access: All CC1311R3 pins are accessible for custom firmware and secondary development.

• Compact Design: Small 24.8 x 18.6 mm SMD package for space-constrained designs.
