Questions
How big is the Dev IO Board PCB?
It measures 127 × 87.6 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Dev IO Board use?
72 parts, built around the 74LS49PC, 1TS005F-2500-5001, TDSR1360 and PS1240P02BT. 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 Dev IO Board KiCad files?
From the jonghee-son/Development_IO_Board repository on GitHub, at the commit this page was made from: the board is Dev_IO_Board.kicad_pcb and its schematic 7seg.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Dev IO Board design in my own project?
Its repository publishes it under the Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
