Questions
How big is the Retro-002 PCB?
It measures 100 × 100 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Retro-002 use?
353 parts, built around the ATF1504AS-10AU100, 74HC14, 74HC04D and 74HC74D. 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 Retro-002 KiCad files?
From the githubgilhad/HW-001 repository on GitHub, at the commit this page was made from: the board is HW/KiCad/retro-002/retro-002.kicad_pcb and its schematic HW/KiCad/retro-001/CrossConnect.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Retro-002 design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
