The WLRS-590 is designed & manufactured in a smallest form factor - SiP ( System in Package ). It integrate with Semtech SX1276 and a 32-bit ultra low power Cortex M0L MCU ( STM32L073x ), supporting global 868 MHz or 915 MHz ISMBands. This WLRS-590SiP Module is a general purpose SiP module for sensor integration. Sensor vendors can speed up their LPWAN integration by embedding this module in their designs. This module will take care of the LPWAN communication with our LPWAN AP and cloud services. There are different integration options: the sensor design can integrate this SMT module via AT command set treating this module as a GPRS modem replacement; the interface can be via UART interface; and the entire sensor be controlled by the MCU of the module through GPIO or I2C or UART.
