Dragino RS485-CB -- RS485/UART to NB-IoT/LTE-M Converter

Product Description

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

RS485-CB can interface to 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-CB supports different uplink methods including MQTT, MQTTs, UDP, TCP or CoAP for different application requirement, and support uplinks to various IoT Servers.

RS485-CB supports BLE configure and OTA update which make user easy to use.

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

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