Bottom: common questions

How big is the Bottom PCB?

The Bottom measures 65 × 120 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Bottom?

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

Where can I download the Bottom design files?

From the not-sample-text/Proiect-Licenta repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Bottom design in my own project?

The repository has no license, so all rights stay with not-sample-text. Use it as a reference, and ask the author before reusing the design.
