MS48-LR-EC25 LoRaWAN to RS485 Bridge

The Dragino MS48-LR-EC25 is an open-source industrial LoRaWAN to Modbus gateway with integrated 4G LTE (EC25 module), designed to bridge LoRaWAN wireless devices with IP and PLC/SCADA systems via Modbus. It supports Ethernet, WiFi, and cellular connectivity, making it ideal for remote and distributed deployments where wired networks are unavailable. With a built-in ChirpStack LoRaWAN server and Node-RED application server, the MS48-LR-EC25 enables fast, standalone IoT system deployment without external cloud dependency.
