Questions
How big is the Core64c LB PCB?
It measures 85 × 85 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Core64c LB use?
162 parts, built around the SN74LV1T125DBVR-TP, SN74HC595DRG3, 74HC02 and LM393. 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 Core64c LB KiCad files?
From the ageppert/Core-64c-Compact-Interactive-Core-Memory-Badge repository on GitHub, at the commit this page was made from: the board is Electronics/Core64c LB V0.6-V0.7 Design KiCAD 8/Core64c LB.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Core64c LB 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).
