Questions

How big is the Environment sensor PCB?

It measures 80 × 75 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Environment sensor use?

110 parts, built around the ATMEGA32U4-AU, DS18B20, W5500 and J1B1211CCD. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the Environment sensor KiCad files?

From the SeanDS/environment-sensor repository on GitHub, at the commit this page was made from: the board is hardware/environment-sensor.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Environment sensor design in my own project?

Its repository states no licence, so its author keeps all rights: ask SeanDS before reusing the design.
