Questions
How big is the Gp mpu PCB?
It measures 302.1 × 188.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Gp mpu use?
221 parts, built around the LM339, 74LS00SC, 74LS377PC and 74LS04PC. 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 Gp mpu KiCad files?
From the jfleitz/gp-mpu repository on GitHub, at the commit this page was made from: the board is gp-mpu.kicad_pcb and its schematic display.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Gp mpu design in my own project?
Its repository states no licence, so its author keeps all rights: ask jfleitz before reusing the design.
