Product Overview


This LPWAN WLRS-592EVB integrates WLRS-592 Sip module that provides ultra-long range spread spectrum communication and high interference immunity.


WLRS-592 is designed & manufactured in a smallest form factor -SiP (System in Package). WLRS-592 integrates with Semtech SX1278 and a 32-bit ultra-low power Cortex M0+ MCU (STM32L073x), supporting 470MHz ISM-Bands.


This product is designed with multiple easy to use interfaces (I2C/SPI/UART/GPIO), For faster development, SparkLAN provides WLRS-592EVB. The WLRS-592EVB 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-592 module provides a commands set interface that can use LoRa and LoRaWAN communication through UART interface.
