Questions
How big is the Visual ADC Relay Block PCB?
It measures 32.9 × 50.2 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Visual ADC Relay Block use?
34 parts, built around the 74HC245D, 74HCT595D and PMV50EPEAR. 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 Visual ADC Relay Block KiCad files?
From the baldengineer/VADC-visualized-adc repository on GitHub, at the commit this page was made from: the board is kicad/Visual ADC Relay Block/Visual ADC Relay Block.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Visual ADC Relay Block 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).
