Questions
How big is the Retro uart PCB?
It measures 17.4 × 51.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Retro uart use?
17 parts, built around the 74LVC1G10DW, 74LVC2G02DC, 74LVC3G04DC and MAX7375AXR805+T. 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 uart KiCad files?
From the rkujawa/retro-uart repository on GitHub, at the commit this page was made from: the board is hardware/retro-uart.kicad_pcb and its schematic hardware/retro-uart.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Retro uart 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).
