Sgkey: common questions

How big is the Sgkey PCB?

The Sgkey measures 91 × 55 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Sgkey?

16 components, from 5 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 Sgkey design files?

From the nobodywasishere/mmp 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 Sgkey design in my own project?

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