Questions
How big is the Tom-1 PCB?
It measures 127 × 127 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Tom-1 use?
83 parts, built around the 74LS245SC, 74LS00SC, 74LS193P-E and 74LS377PC. 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 Tom-1 KiCad files?
From the tcr/tom-1 repository on GitHub, at the commit this page was made from: the board is kicad/tom-1.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Tom-1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask tcr before reusing the design.
