Overview

The WLR089U0-I/RM is an ultra-low power LoRa module based on the ATSAMD21G18 sub-GHz radio SoC, integrating a 48MHz ARM Cortex-M0+ processor and a high-performance LoRa transceiver. It supports global sub-GHz frequency bands from 863MHz to 928MHz and features a U.FL connector for flexible antenna options.

Why Choose This Part

This module combines a low-power 32-bit MCU with 256kB of Flash and 32kB of SRAM, eliminating the need for an external host controller. It provides excellent sensitivity of -136dBm and up to 18.5dBm output power, ensuring reliable long-range communication while operating on a wide supply voltage of 1.8V to 3.5V.

Applications

Smart Agriculture
Long-range soil moisture and environmental monitoring in rural areas where cellular coverage is unavailable.
Industrial IoT
Predictive maintenance and sensor telemetry for factory assets located in RF-challenging environments.
Remote Utility Metering
Automated reading of gas, water, and electricity meters over city-wide LPWAN networks.
Asset Tracking
Battery-powered tracking of logistics containers and equipment across large shipping yards or construction sites.
