Questions
How big is the SHS Engineering Business Card PCB?
It measures 85.7 × 58 mm and has 2 copper layers, 1.6 mm thick.
What parts does the SHS Engineering Business Card use?
66 parts, built around the RP2040, W25Q128JVSIQ, WS2812B and ABM8-272-T3. 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 SHS Engineering Business Card KiCad files?
From the duddybuddy/SantanaEngineeringPCBA repository on GitHub, at the commit this page was made from: the board is SHS Engineering Business Card PWA Rev B/SHS Engineering Business Card.kicad_pcb and its schematic SHS Engineering Business Card PWA Rev B/SHS Engineering Business Card.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the SHS Engineering Business Card design in my own project?
Its repository states no licence, so its author keeps all rights: ask duddybuddy before reusing the design.
