SN50v3-NB is a Long Range NB-IoT Sensor Node.  It is designed to facilitate developers' quick deployment of industrial-level NB-IoT solutions. It helps users turn an idea into a practical application and make the Internet of Things a reality. It is easy to program, create, and connect things everywhere.

The SN50v3-NB wireless part is based on the NB model, which 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 minimizing current consumption. It targets professional wireless sensor network applications such as irrigation systems, smart metering, smart cities, building automation, etc.

SN50v3-NB uses an STM32l0x chip from ST, STML0x is the ultra-low-power STM32L072xxxx microcontrollers incorporate the connectivity power of the universal serial bus (USB 2.0 crystal-less) with the high-performance ARM® Cortex®-M0+ 32-bit RISC core operating at a 32 MHz frequency, a memory protection unit (MPU), high-speed embedded memories (192 Kbytes of Flash program memory, 6 Kbytes of data EEPROM and 20 Kbytes of RAM) plus an extensive range of enhanced I/Os and peripherals.

SN50v3-NB is an open-source product, it is based on the STM32Cube HAL drivers and lots of libraries can be found on the ST site for rapid development.

SN50v3-NB supports different uplink methods including MQTT, MQTTs, UDP & TCP for different application requirements, and supports uplinks to various IoT Servers.

SN50v3-NB supports BLE configure and OTA update which makes users easy to use.

SN50v3-NB is powered by an 8500mAh Li-SOCI2 battery, it is designed for long-term use up to several years.

SN50v3-NB has an optional built-in SIM card and default IoT server connection version. Which makes it work with a simple configuration.
