Microchip’s WLR089U0 Module, Now at Mouser


Mouser Electronics, Inc., the industry’s leading New Product Introduction (NPI) distributor with the widest selection of semiconductors and electronic components, is now stocking the WLR089U0 LoRa®-enabled sub-GHz module from Microchip Technology. Featuring ultra-low-power sleep currents as low as 790 nA, the WLR089U0 module provides an ideal solution for battery-powered remote sensing applications, including Internet of Things (IoT) devices and smart city solutions.

The Microchip WLR089U0 module, available from Mouser Electronics, is based on the highly integrated SAM R34 family ICs with support for LoRa and FSK modulation. The WLR089U0 module includes a 32-bit Arm® Cortex®-M0+ processor and includes 256 Kbytes of flash and 40 Kbytes of SRAM (including 8 Kbytes of battery-backed SRAM). The highly configurable module offers a wide range of peripherals, including seven 12-bit analog-to-digital converter (ADC) channels, up to four serial communication interfaces, and two analog comparators.

The WLR089U0 module integrates an RF switch to support worldwide LoRaWAN operation from 863 MHz to 928 MHz, allowing developers to use a single part variant across different regions, simplifying the design process and streamlining the bill of materials. The module delivers up to 18.6 dBm of transmit (TX) power with an receive (RX) sensitivity down to -136 dBm, and is certified to FCC (U.S.), IC (Canada), and RED/CE (Europe).

Mouser also stocks the WLR089 Xplained Pro evaluation kit, which provides easy access to various features of the WLR089U0 module and ATSAMR34J18B device and offers additional peripherals to extend the features of the board and ease the development of custom designs. The kit is supported by the Atmel Studio, an integrated development platform, which provides predefined application examples.
