Questions
How big is the Adc PCB?
It measures 99.7 × 99.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Adc use?
234 parts, built around the SM4T15AY. 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 Adc KiCad files?
From the FrankBuss/adc4 repository on GitHub, at the commit this page was made from: the board is kicad/adc/adc.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Adc design in my own project?
Its repository states no licence, so its author keeps all rights: ask FrankBuss before reusing the design.
