Materials
Within this page you can see all of the required materials for building the base unit, as well as the materials for adding sensors and other 'accessory' nodes. If you already have some of these pieces, for example, a 3d printer, you don't need to factor that into the cost. We have included every sensor that we currently support for the station within this list. If you have other sensors you wish to include, we would be thrilled for you to modify the codebase and send us a pull request or send a comment to us via our Contribution portal.

Optional Materials
A note on optional materials. If you are hosting in a sunny place and running your station with a relatively low power configuration, you can use a smaller solar panel and battery (below). Additionally, for better print quality, a PEI plate can be quite nice, although not necessary by any means.
