The MCCI Catena® 4450 Node for LoRaWAN™ technology is a powerful open-source IoT device designed specifically for use with The Things Network. Based on the Adafruit Feather M0 system, the Catena 4450 is a ready-to-use platform for LoRaWAN 1.0 and 1.1 wireless IoT applications.
Although it's available in several variants, the recommended base configuration consists of:
The Adafruit Feather M0 board. Features: ARM Cortex M0 CPU at 48 MHz 256 kilobytes of flash program memory 32 kilobytes of static RAM 900 MHz LoRa® radio from Hope RF USB port for charging and programming Compatible with a wide range of Adafruit Feather Wings Battery charging circuit for LiPo batteries Fifteen I/O pins with a variety of supported protocols
The Catena 4450 sensor daughterboard, including: Configuration jumpers for optimum performance with LoRaWAN; 2 kbytes of ferro-electric RAM (FRAM) for non-volatile storage of network parameters, session keys, and application data (fully meeting requirements of LoRaWAN 1.1); A Bosch BME-280 sensor, measuring temperature, humidity, and barometric pressure; A lux sensor, measuring from 0 to 65,536 lux of ambient light; An I2C expansion multiplexer, for adding additional I2C devices externally; Screw terminals (on the M101 and M102 assembled models) for connecting external sensors.
