Alu: common questions

How big is the Alu PCB?

The Alu measures 207 × 132.1 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Alu?

290 components, from 7 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Alu design files?

From the bmichini/nandirl repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Alu design in my own project?

The repository has no license, so all rights stay with bmichini. Use it as a reference, and ask the author before reusing the design.
