SN50v3-CB - NB-IoT/LTE-M Digital Sensor Node

Dragino SN50v3-CB is a NB-IoT and LTE-M Digital Sensor Node for Internet of Things. It has 5V output to power an external sensor, 3 interrupt inputs (or 3 digital I/O), 3 one-wire, 1 UART and 1 I2C interfaces. The node will convert the values to NB-IoT or LTE-M wireless data and send to IoT platform via a NB-IoT/LTE-M network.

You can use various IoT Servers and different uplink methods including MQTT, MQTTs, UDP and TCP. 

The sensor node uses Quectel BG95-NGFF Multi-band LTE Cat M1/Cat NB2 module with GPS which can be used in most European countries. It has a card slot for an NB-IoT/LTE-M SIM card. Ask your mobile operator about availability of SIM cards, coverage, frequencies used and login procedures. See for example Deutsche Telekom IoT and 1NCE.

This device supports BLE for easy configuration and wireless OTA to update the firmware.

SN50v3-CB is powered by 8500mAh Li-SOCI2 battery for many years of use. It has an external antenna and an IP66 enclosure with a waterproof M12 cable hole for an external sensor.
