How to Buy

Pricing starts at $45/unit.

The MCCI Catena® 4802 RS-485/Sensor 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, while also monitoring temperature and humidity with an integrated Sensirion SHT31 sensor. It also incorporates a JST 4-pin connector for easy connection of external I2C devices following the Sparkfun Qwiic system.

Based on the Murata CMWX1ZZABZ-078, the Catena 4802 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 4802 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 4802 can bridge an existing Modbus controller to the LoRaWAN network.

The standard model includes a U.FL connector. Flexible U.FL whip antennas are included in region-specific models. 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.

Volume discounts and custom variants are available. Contact MCCI via email ( for assistance.
