Product Overview

 

The WLRS-592 is designed & manufactured in a smallest form factor -SiP (System in Package). The WLRS-592 integrates with Semtech SX1278 and a 32-bit ultra-low power Cortex M0+ MCU (STM32L073x).

 

The WLRS-592 is a general purpose SiP for sensor integration. Sensor vendors can speed up their LPWAN integration by embedding this SiP in their design. The WLRS-592 can achieve a sensitivity of over -138dBm.

The high sensitivity combined with the integrated +20dBm power amplifier yields industry leading link budget marking it optimal for any low data rate application requiring range or robustness.

 

The WLRS-592 is based on LoRa technology to provides low power long range high sensitivity communication using spread spectrum. The WLRS-592 also provides significant advantages in both blocking and selectivity over conventional modulation techniques, solving the traditional design compromise between range, interference immunity and energy consumption. WLRS-592 module provides a commands set interface that can use LoRa and LoRaWAN communication through UART interface.
