Perfect for LoRaWAN solutions: new WLR089U0 module and WLR089 Xplained Pro Evaluation Kit


Microchip is one of the most respected members of the LoRa Alliance. In the article below, we will present you another proposal from the Microchip portfolio, the latest WLR089U0 module and the WLR089 Xplained Pro Evaluation Kit.


The WLR089U0 module is an ultra-low power, regulatory certified LoRa module based on the ATSAMR34J18 LoRa IC. This module includes a 32-bit ARM Cortex-M0+ processor and offers 256KB of Flash and 40KB of SRAM (8KB battery backed) in a compact 17 x 13.5 mm package.  

With ultra-low power sleep currents as low as 790nA, the WLR089U0 modules are ideal for battery powered remote sensor applications. 

The module operates from 863 to 928 MHz and is FCC, IC and RED certified.  

Supported by WLR089 Xplained Pro Evaluation Kit (EV23M25A), Atmel Studio and a detailed module reference design package, these modules highly simplify the development and accelerate the time to market for LoRa end-nodes.

WLR089 Xplained Pro 


The WLR089 Xplained Pro is a hardware platform designed to evaluate the WLR089U0 LoRa modules. 

The WLR089U0 modules are FCC, IC and RED certified.  This kit is not only an evaluation platform but also an excellent reference design for developing SAMR34/35 based LoRa end-node applications.

This kit is supported by the Atmel Studio, an integrated development platform, which provides predefined application examples.
