This repository contains hardware information about MCCI's open-source hardware designs for Catena LoRaWAN projects.
All schematics are prepared with KiCad, an open-source hardware design package that is freely available. Schematics can be found in the kicad/ subdirectory.
| Directory or file | Contents |
|---|---|
| doc/hualian-sensors.xlsx | the project planning document - BOMs, pricing, planning information. |
| doc/hualian-garden.mm | the FreeMind mind-map used for planning the project. Very useful for reference. |
| kicad/pond-soil-proto/ | the generic Catena 4410, used as a base design for the other sensor nodes. Integrated lux/temperature/pressure/humidity; external I2C, Dallas Semi OneWire, and specialized two-wire interface. In the end, all hardware was identical and based on this. |
| kicad/Catena-4410-greenhouse/ | the greenhouse sensor: integreated lux/temperature/pressure/humidity, plus external soil temperature/humidity |
| kicad/Catena-4410-mushroom/ | the mushroom-house sensor: integrated lux/temperature/pressure/humidity. |
| kicad/Catena-4410-seaweed/ | the seaweed-house sensor: integrated lux/temperature/pressure/humidity, plus external water temperature. |
| kicad/lib/ | the library of common shapes |
| kicad/radio-feather-proto/ | AKA the Catena 4420; this design combines an Adafruit Feather M0 BTLE with a separate Feather RadioWing to form a map-the-things node. Code is on branch MCCI-Catena of https://github.com/mcci-catena/mapthethings-arduino.git |
| kicad/solar-panel-0w5-usb/ | the solar panel design for charging the LiPo batteries. |
| kicad/Catena-4450/ | Catena 4450 wing schematic and PCB layout documents. Also contains Catena 4450 M102 Assembly instructions. |
| kicad/Catena-4551/ | Catena 4551 schematic, Pinout Drawing and other related documents |
Software for most of these (apart from the radio-feather-proto) can be found starting here: https://github.com/mcci-catena/Catena4410-Sketches. Look particularly at Catena4410_Sensor1.ino, catena4450m101_sensor.ino. All the other repos used are forked and available from https://github.com/mcci-catena.
