RS485-LB LoRaWAN RS485/UART Converter Node 868MHz

With the RS485-LB LoRaWAN RS485 Converter Node, you can seamlessly integrate your RS485 or UART sensors into your IoT network. This waterproof device, offering both 3.3V and 5V output, is designed for long-term use. Equipped with an 8500mAh Li-SOCI2 battery, the RS485-LB ensures reliable and energy-efficient data transmission over the LoRaWAN network. Thanks to BLE configuration support and OTA updates, you can easily manage and update the device. This sensor node is the third generation and offers a mature LoRaWAN stack as well as application software. You can use the pre-installed software for your IoT projects or flexibly adapt the software to different requirements.

Each sensor is preloaded with a set of unique keys for LoRaWAN registrations. These keys are registered on the local LoRaWAN server and the sensor automatically connects upon power up when network coverage is available.
