Questions
How big is the WiFi VFD PCB?
It measures 93 × 20 mm and has 2 copper layers, 1.6 mm thick.
What parts does the WiFi VFD use?
23 parts, built around the CH330N, ESP-12S and DHT11. 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 WiFi VFD KiCad files?
From the ciisaichan/WiFi-VFD repository on GitHub, at the commit this page was made from: the board is hardware/wifivfd.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the WiFi VFD design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
