Questions

How big is the Multiplier PCB?

It measures 19 × 100 mm and has 4 copper layers, 1.6 mm thick.

What parts does the Multiplier use?

54 parts, built around the MC1496D and B140-E3. 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 Multiplier KiCad files?

From the xdylanm/multiply-accumulate repository on GitHub, at the commit this page was made from: the board is hardware/multiplier/multiplier.kicad_pcb and its schematic hardware/multiplier/multiplier.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Multiplier 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).
