A2d: common questions

How big is the A2d PCB?

The A2d measures 70 × 45 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the A2d?

56 components, from 14 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 A2d design files?

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

Can I use the A2d design in my own project?

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