Hat: common questions

How big is the Hat?

The Hat measures 65 × 56 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Hat?

81 components, from 40 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 Hat design files?

From the pa3gsb/Radioberry-2.x 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 Hat design in my own project?

The repository has no license, so all rights stay with pa3gsb. Use it as a reference, and ask the author before reusing the design.
