Questions
How big is the Tww PCB?
It measures 77 × 77 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Tww use?
58 parts, built around the ESP-12F, HLK-PM01, DS18B20 and G3MB-202PL. 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 Tww KiCad files?
From the stan23/tww-control repository on GitHub, at the commit this page was made from: the board is PCB/tww/tww.kicad_pcb and its schematic PCB/tww/tww.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Tww design in my own project?
Its repository states no licence, so its author keeps all rights: ask stan23 before reusing the design.
