Dragino RS485-LB RS485 / UART to LoRaWAN Converter with IP67 Waterproof Rating

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

RS485-LB can interface to RS485 sensor, 3.3v/5v UART sensor or interrupt sensor. RS485-LB 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-LB is IP67 waterproof and powered by 8500mAh Li-SOCI2 battery, it is designed for long term use for several years.

RS485-LB runs standard LoRaWAN 1.0.3 in Class A. It can reach long transfer range and easy to integrate with LoRaWAN compatible gateway and IoT server.

RS485-LB Supports BLE configure and wireless OTA update which make user easy to use.
