    RS485-NB RS485/UART to NB-IoT Converter Sensor Node

    The Dragino RS485-NB is a RS485 / UART to NB-IoT Converter for Internet of Things solutions. User can connect the RS485 or UART sensor to the RS485-NB converter, and configure RS485-NB to periodically read sensor data and upload via NB-IoT network to IoT server.

    RS485-NB can interface to the RS485 sensor, 3.3v/5v UART sensor, or interrupt sensor. RS485-NB provides a 3.3v output and a 5v output to power external sensors. Both output voltages are controllable to minimize the total system power consumption.

    RS485-NB supports different uplink methods including MQTT, MQTTs, UDP & TCP for different application requirement, and support uplinks to various IoT Servers.

    RS485-NB supports BLE configure and OTA update which make users easy to use.

    RS485-NB is powered by an 8500mAh Li-SOCI2 battery, it is designed for long-term use up to several years.

    RS485-NB has an optional built-in SIM card and default IoT server connection version. Which makes it work with simple configuration.
