Questions
How big is the Anavi thermometer PCB?
It measures 74.9 × 40.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Anavi thermometer use?
25 parts, built around the ESP-12E, DHT22, DS18B20 and LD1117S33TR(MS). 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 Anavi thermometer KiCad files?
From the AnaviTechnology/anavi-thermometer repository on GitHub, at the commit this page was made from: the board is anavi-thermometer.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Anavi thermometer design in my own project?
Its repository states no licence, so its author keeps all rights: ask AnaviTechnology before reusing the design.
