Converter waterproof Dragino RS485-LB RS485/UART to LoRaWAN

RS485-LB is an RS485/UART to LoRaWAN converter for IoT solutions. The user can connect an RS485 or UART sensor to the RS485-LB converter and configure the RS485-LB to periodically read the sensor data and upload it via LoRaWAN to the IoT server. The RS485-LB can be connected to an RS485 sensor, a 3.3V/5V UART sensor, or an interrupt sensor. The RS485-LB provides a 3.3V output and a 5V output to power external sensors. Both output voltages can be controlled to minimize overall system power consumption. The RS485-LB is IP67 waterproof and powered by an 8500mAh Li-SOCI2 battery, so it is designed to last for several years. RS485-LB works with LoRaWAN 1.0.3 standard in class A. It can achieve long transmission range and easily integrates with LoRaWAN compatible gateway and IoT server. To transfer data, the RS485-LB sends user-defined commands to RS485 devices and receives responses from RS485 devices. The RS485-LB will process this return data according to user-defined rules to obtain the final payload and upload it to the LoRaWAN server. For the data downlink, the RS485-LB works in LoRaWAN class A. When there are downlink commands to the LoRaWAN server, the RS485-LB forwards the commands from the LoRaWAN server to the RS485 device. RS485-LB Supports BLE configuration and wireless OTA update, which makes the user easy to use. Each RS485-LB will pre-download a set of unique LoRaWAN registration keys, register these keys with the LoRaWAN server, and it will automatically connect after power-on.
