Device Overview

Summary

The WLR089U0 module is an ultra-low power, regulatory certified LoRa module based on the ATSAMR34J18 LoRa IC. This standalone 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 highly configurable module peripherals include up to 4 SERCOMs (configurable as I2C/SPI /UART/LIN interfaces) with one in the low power domain, 7 12-bit ADC channels and 2 analog comparators. The module supports LoRa, FSK, MSK and OOK modulations and delivers up to 18.6 dBm TX power with an RX sensitivity down to -136 dBm.

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.
