SparkLAN Wireless IoT Low Power Wide Area Network (LPWAN) Technologies And Solutions / WLRS-590, WLRS-591

WLRS-590 is the first sub-1GHz SparkLAN wireless module, which is designed & manufactured in a smallest form factor -SiP (System in Package) that is a general purpose SiP for sensor integration.

WLRS-590 is the first sub-1GHz SparkLAN wireless module, which is designed & manufactured in a smallest form factor -SiP (System in Package) that is a general purpose SiP for sensor integration. Sensor vendors can speed up their LPWAN integration by embedding this SiP in their design, and WLRS-590 featuring the Semtech’s LoRa long range providing ultra-oong range spread spectrum communication and high interference immunity whilst minimizing current consumption.

WLRS-590 can be configured as an embedded micro system or simple data for low power applications in the 863-928 MHz radio band. It is based on Semtech SX1276 transceiver coupled with STM32L073xZ ARM Coretex-M0+ 32-bit MCU, equipped with up to 192 KB of flash memory and up to 20 KB RAM memory.

WLRS-590 can communicate with other devices through a wide range of serial interfaces: UART, I2C and SPI ports, several digital and analog I/T ports useful for the management of external devices and interfaces.

Using Semtech’s patented LoRa modulation technique SX1272 can achieve a sensitivity of over -137dBm. The high sensitivity combined with the integrated power amplifier yields industry leading link budget, making it optimal for any application requiring long range and link robustness. LoRa also provides significant advantages in both blocking and selectivity capabilities over all conventional modulation techniques, improving the traditional design compromises between coverage, interference immunity and energy consumption.

For faster development, SparkLAN provides an evaluation board named WLRS-591. integrates WLRS-590 that provides a commands set interface that can use LoRa and LoRaWAN communication through UART interface which have ultra –long range spread spectrum communication and high interference immunity. 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.

The LoRA - WLRS-590/WLRS-591 is ideally suitable for 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 for any low data rate application requiring range or robustness.
