Questions
How big is the DesktopToy PCB?
It measures 44 × 35.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the DesktopToy use?
44 parts, built around the ESP32-S3-WROOM-1-N8, VEML7700-TT, KT148A and LP5907MFX-1.8. 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 DesktopToy KiCad files?
From the KisonHe/DesktopToy-pcb repository on GitHub, at the commit this page was made from: the board is DesktopToy/DesktopToy.kicad_pcb and its schematic DesktopToy/DesktopToy.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the DesktopToy design in my own project?
Its repository publishes it under the GPL-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
