SN50V3-LB LoRaWAN Sensor Node is a Long Range LoRa Sensor Node. It is designed for outdoor use and powered by 8500mA Li/SOCl2 battery for long term use.SN50V3-LB is designed to facilitate developers to quickly deploy industrial level LoRa and IoT solutions. It help users to turn the idea into a practical application and make the Internet of Things a reality. It is easy to program, create and connect your things everywhere.

SN50V3-LB wireless part is based on SX1262 allows the user to send data and reach extremely long ranges at low data-rates.It provides ultra-long range spread spectrum communication and high interference immunity whilst minimising current consumption.It targets professional wireless sensor network applications such as irrigation systems, smart metering, smart cities, smartphone detection, building automation, and so on.

SN50V3-LB has a powerful 48Mhz ARM microcontroller with 256KB flash and 64KB RAM. It has multiplex I/O pins to connect to different sensors.

SN50V3-LBhas a built-in BLE module, user can configure the sensor remotely via Mobile Phone. It also support OTA upgrade via private LoRa protocol for easy maintaining.

SN50V3-LB is the 3^rd generation of LSN50 series generic sensor node from Dragino. It is an open source project and has a mature LoRaWAN stack and application software. User can use the pre-load software for their IoT projects or easily customize the software for different requirements.
