Product Overview

 

This LPWAN WLRS-591EVB integrates WLRS-590 that provides ultra –long range spread spectrum communication and high interference immunity.

 

The WLRS-590 is designed & manufactured in a smallest form factor -SiP (System in Package). WLRS-590 integrates with Semtech SX1276 and a 32-bit ultra-low power Cortex M0+ MCU (STM32L073x), supporting 863-915MHz ISM-Bands.

 

This product is designed with multiple easy to use interfaces (I2C/SPI/UART/GPIO), For faster development, SparkLAN provides WLRS-591EVB. The EVB equips with a UART-To-USB bridge IC and can be powered by USB. Besides, a SMA antenna connector is also provided for easy antenna installation. WLRS-590 module provides a commands set interface that can use LoRa and LoRaWAN communication through UART interface.
