MCHPWLR089U0-I/RM
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
Key Specifications
Getting Started
Developers can use the SAM R34/R35 family of software tools, including Microchip Studio and the Advanced Software Framework (ASFv3). Hardware evaluation is best performed using the WLR089 Xplained Pro evaluation kit, which provides access to the 23 GPIO pins and supports programming via the integrated SWD interface.
