MCCI Catena® 4801 RS-485 node
The MCCI Catena 4801 RS-485 Node for LoRaWAN® technology networks is a complete open-source single-board IoT device that can monitor and control remote Modbus, M-Bus and other industrial devices.
Based on the Murata CMWX1ZZABZ-078, the Catena 4801 is a great platform for RS-485/Modbus based LoRaWAN investigation and deployment. It works well with The Things Network, or any LoRaWAN 1.0 or 1.1 network in the 865 to 923 MHz range.
As a Modbus controller, the Catena 4801 can control a large number of Modbus devices and communicate results via the LoRaWAN network, limited only by system memory and polling rate. As a Modbus device, the Catena 4801 can bridge an existing Modbus controller to the LoRaWAN network.
The standard model includes a U.FL connector. Other variants are available on request.
Software development requires an ST-LINK/V2 or equivalent, plus an USB to serial adapter. MCCI's Catena Development Starter Kit includes everything needed.
