The MCCI Catena® 4470 Modbus Node for LoRaWAN™ technology is a powerful open-source IoT device that integrates Modbus control with The Things Network. Based on the Adafruit Feather M0 system, the Catena 4470 is a ready-to-use platform for Modbus-oriented LoRaWAN 1.0 and 1.1 wireless IoT applications.
The Catena 4470 can also be used to add Modbus and sensing to any member of the Adafruit Feather system.
