Questions
How big is the DigitalLogicProject PCB?
It measures 96 × 96 mm and has 2 copper layers, 1.6 mm thick.
What parts does the DigitalLogicProject use?
102 parts, built around the ATMEGA88PB-AU, LTST-S220GKT, LTD-4708G and RDS-16S-1055-SMT. 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 DigitalLogicProject KiCad files?
From the Jetsama/DigitalLogicProject repository on GitHub, at the commit this page was made from: the board is PCBS/BOARD/BOARD.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 DigitalLogicProject design in my own project?
Its repository states no licence, so its author keeps all rights: ask Jetsama before reusing the design.
