LSN50V3 SN50V3-LB built-in BLE support OTA upgrade LoRaWAN Sensor Node

SN50V3-LB is the 3rd generation of the 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.

SN50V3-LB LoRaWAN Sensor Node is a Long Range LoRa Sensor Node. It is designed for outdoor use and powered by an 8500mAh Li/SOCl2 battery for long-term use.SN50V3-LB is designed to facilitate developers to quickly deploy industrial-level LoRa and IoT solutions. It helps 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, allowing 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 minimizing 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 48 MHz ARM microcontroller with 256KB flash and 64KB RAM. It has multiplex I/O pins to connect to different sensors.

SN50V3-LB has a built-in BLE module, the user can configure the sensor remotely via a  Mobile Phone. It also supports OTA upgrades via private LoRa protocol for easy maintenance.
