Questions
How big is the DISPLAY PCB?
It measures 30 × 15 mm and has 2 copper layers, 1.6 mm thick.
What parts does the DISPLAY use?
17 parts, built around the ATMEGA88PB-AU and LTD-4708G. 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 DISPLAY KiCad files?
From the Jetsama/DigitalLogicProject repository on GitHub, at the commit this page was made from: the board is PCBS/DISPLAY/DISPLAY.kicad_pcb and its schematic Gates/NOTGATE/NOTGATE.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the DISPLAY design in my own project?
Its repository states no licence, so its author keeps all rights: ask Jetsama before reusing the design.
