RS485-LB RS485 to LoRaWAN Converter

The Dragino RS485-LB is an industrial-grade RS485/UART to LoRaWAN converter designed to connect RS485 or UART-based sensors to a LoRaWAN network. It periodically polls connected devices (including Modbus sensors), processes returned data using user-defined rules, and transmits the payload to an IoT server over long-range, low-power LoRaWAN. With an IP67 waterproof enclosure and long-life battery, it is well suited for outdoor and industrial deployments.
