N560AS S2LP Narrowband RF Module
Product Overview
The N560AS is a high-performance, ultra-low power narrowband RF transceiver module based on STMicroelectronics' S2-LP chip. Engineered for reliable, long-range communication in license-free Sub-1 GHz bands, it operates in key 433 MHz, 868 MHz, and 915 MHz ISM/SRD frequencies. The module delivers +16 dBm output power and -126 dBm receiver sensitivity, achieving an excellent RF link budget exceeding 140 dB. Its support for narrow channel spacing (down to 1 kHz) and programmable data rates (0.1 to 500 kbps) makes it an ideal solution for applications requiring robust, spectrally efficient wireless links in industrial, metering, and IoT networks.
Key Features & Benefits
Superior Narrowband Performance: Optimized for stable, long-range communication with minimal interference, supporting channel spacing as low as 1 kHz for efficient spectrum use.
Exceptional Link Budget: A combination of +16 dBm power and -126 dBm sensitivity delivers a link budget over 140 dB, enabling reliable connections up to 2 km in open environments.
Ultra-Low Power Operation: Consumes only 12 mA in receive mode and as low as 1 µA in sleep mode, making it perfect for battery-powered devices requiring years of service.
Global Frequency Flexibility: Programmable to operate in major global bands (433/470/868/915 MHz) and easily adapted to meet regional regulatory requirements (ETSI, FCC, etc.).
Compact & Developer-Friendly: All S2-LP control and GPIO pins are broken out in a compact 20 x 17 mm form factor, offering full flexibility for custom firmware and hardware integration via a standard SPI interface.
