Questions

How big is the Registers Module PCB?

It measures 95.9 × 90.2 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Registers Module use?

45 parts, built around the 74LS245SC and 74LS173SC. 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 Registers Module KiCad files?

From the uddivert/SAP-U repository on GitHub, at the commit this page was made from: the board is Registers_Module/Registers_Module.kicad_pcb and its schematic Arithmetic_Logic_Unit/ALU.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Registers Module design in my own project?

Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
