Wireless RF Modules and dongles for IoT | Coral RF

The N562AS is a versatile and high-performance RF transceiver module engineered around the STMicroelectronics S2-LP, an ultra-low power RF transceiver IC. Enhanced with an external Power Amplifier (PA) and Low-Noise Amplifier (LNA), this module delivers a powerful combination of +33 dBm (2W) output power and excellent -126 dBm receiver sensitivity. Designed for reliable, long-range narrowband communication, it supports key global ISM bands including 433 MHz, 868 MHz, and 915 MHz. With a flexible data rate from 0.1 to 500 kbps and support for narrowband operation down to 1 kHz channel spacing, the N562AS is perfectly suited for demanding applications in smart metering, industrial telemetry, and wide-area sensor networks, meeting regulatory requirements worldwide.

Key Features & Benefits

Exceptional Link Budget: +33 dBm transmit power combined with -126 dBm sensitivity provides a robust link budget exceeding 140 dB, enabling reliable communication over distances up to 12 km.
Ultra-Low Power Consumption: Based on the inherently low-power S2-LP core, the module features a low RX current (14 mA) and deep sleep current (1 µA), making it ideal for battery-operated devices.
Global Narrowband Compliance: Supports programmable narrowband operation with channel spacing down to 1 kHz, essential for meeting strict spectral efficiency regulations in regions like Europe and for professional licensed band use.
Wide Frequency & Data Rate Flexibility: The S2-LP core can be programmed for operation from 413-479 MHz, 826-958 MHz, and 904-1055 MHz, with data rates from 0.1 to 500 kbps, offering unparalleled application versatility.
Complete Design Control: All S2-LP control and GPIO pins are broken out, including dedicated RFT, RFR, LNAC, and VTCXO pins, providing maximum flexibility for advanced RF front-end control and system integration.
