Questions
How big is the Segment 60 PCB PCB?
It measures 285.8 × 133.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Segment 60 PCB use?
131 parts, built around the ATMEGA328P-PU, 74HC365D and 74HC138. 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 Segment 60 PCB KiCad files?
From the slonket/segment-keyboard repository on GitHub, at the commit this page was made from: the board is segment_60_PCB/segment_60_PCB.kicad_pcb and its schematic segment_60_PCB/segment_60_BREAKOUT/segment_60_BREAKOUT.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Segment 60 PCB 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).
