Keypad: common questions

How big is the Keypad PCB?

The Keypad measures 100 × 100 mm, has 4 copper layers and is 1.5854 mm thick.

How many components are on the Keypad?

82 components, from 8 distinct parts. The full bill of materials is listed on this page.

Where can I download the Keypad design files?

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

Can I use the Keypad design in my own project?

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