Questions
How big is the Wzhooh PCB?
It measures 75.1 × 85 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Wzhooh use?
47 parts, built around the DA08-11SURKWA and ULN2803A. 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 Wzhooh KiCad files?
From the dotcypress/wzhooh repository on GitHub, at the commit this page was made from: the board is pcb/wzhooh.kicad_pcb and its schematic pcb/wzhooh.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Wzhooh design in my own project?
Its repository publishes it under the Apache-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).
