Overview

The GAMMA62T-89S is a high-performance LoRa radio module from RF Solutions designed for long-range communication in the 868MHz and 918MHz ISM bands. It leverages LoRa spread spectrum technology to achieve exceptional sensitivity of -148dBm and a power output up to 22dBm, enabling reliable data transmission over several kilometers. The module is provided in a surface-mount 31-SMD package and operates across a wide supply voltage range of 2.4V to 3.6V.

Why Choose This Part

This module provides 5V tolerant I/O, which simplifies integration with a variety of microcontrollers without needing external level shifters. Its low sleep current of 1uA makes it highly suitable for battery-powered end-nodes requiring multi-year lifespans.

Applications

Long-Range Remote Control
Ideal for industrial switching and control systems requiring robust links in electrically noisy environments.
Agricultural Monitoring
Suitable for soil moisture sensors and livestock tracking across large outdoor areas where cellular coverage is unavailable.
Smart Metering
Used in utility meters for wireless data collection through building walls and dense urban structures.
