The grid design files

The KiCad project lives in the asterane/the-grid repository on GitHub; these links point at the commit this page was built from.

The grid: common questions

How big is the The grid PCB?

The The grid measures 76.2 × 45.7 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the The grid?

54 components, from 7 distinct parts. The full bill of materials is listed on this page.

Where can I download the The grid design files?

From the asterane/the-grid repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the The grid design in my own project?

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