MCCI Catena® 4460 LoRaWAN™ Node w/ BME680 VOC Sensor
The MCCI Catena® 4460 Sensor Wing is a flexible open-source IoT device wing designed specifically for use with the Adafruit Feather M0 LoRa system, but suitable for use with any Adafruit Feather CPU board. Like the Catena 4450, when combined with a suitable CPU, it is a ready-to-use platform for LoRaWAN™ 1.0 and 1.1 wireless IoT applications.
Its key feature is integration of a Bosch BME680 Integrated Environmental Sensor, capable of monitoring temperature, humidity, pressure, and volatile organic compounds (VOC). When used with suitable drivers, the BME680 can produce a simple air-quality index.
The Catena 4460 sensor wing has the following features.
- Integrated jumpers to make the Feather M0 LoRa work with the Arduino LMIC without further modification or wiring -- just plug on the Catena 4460.
- 2 kbytes of ferro-electric RAM (FRAM) for non-volatile storage of network parameters, session keys, and application data (fully meeting requirements of LoRaWAN 1.0.2 and 1.1).
- A Bosch BME680 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.
- Provisions for screw terminals (not included) for terminating external sensors.
The WING-ONLY variant is the Catena 4460 wing only. It does not include the CPU board, nor does it include headers or screw terminals. It is great for experimenters who want to breadboard more complex solutions.
The DIY-KIT is a complete IoT node ready for assembly. It includes:
- Catena 4460 board
- Adafruit Feather M0 LoRa 900 and header pins
- Female headers (12 and 16 pin)
- 350 mAh LiPo battery
- Two 4-position screw terminals
- 64-bit EUI sticker
- Whip antenna for 915 MHz (will work pretty well for 868, but we recommend a longer antenna for use in Europe or India).
All you need to do is solder it together (takes about half an hour), add is a USB cable and the Arduino development environment, and you're ready to write code.
The DIY-FACTORY is the same as the DIY-KIT, except that it's fully assembled and tested by MCCI.
