The WLRS-590 is designed & manufactured in a smallest form factor -SiP (System in Package). The WLRS-590 integrates with Semtech SX1276 and a 32-bit ultra-low power Cortex M0+ MCU (STM32L073x)

The WLRS-590 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-590 can achieve a sensitivity of over -137dBm.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-590 is based on LoRa technology to provides low power long range high sensitivity communication using spread spectrum. The WLRS-590 also provides significant advantages in both blocking and selectivity over conventional modulation techniques, solving the traditional design compromise between range, interference immunity and energy consumptionWLRS-590 module provides a commands set interface that can use LoRa and LoRaWAN communication through UART interface.

Suitable Application
Application range including automated meter reading, industrial monitoring and control, traffic detection and control, intelligent parking, street lighting management, irrigation control, forest fire detection, air pollution, earthquake, intelligent tracking, etc
