The Dragino SN50v3-NB - NB-IoT Sensor Node is a Long Range NB-IoT Sensor Node. It is designed to facilitate developers to deploy industrial-level NB-IoT solutions quickly. 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-NB wireless part is based on NB model 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 while 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 in ST site for rapid development.
