The little wing keyboard sources

This my attempt to build a better keyboard for myself.

Think of it as a 32% split bluetooth keyboard merged with the classic MX Ergo trackball

Sensor: common questions

How big is the Sensor PCB?

The Sensor measures 34.9 × 19 mm, has 4 copper layers and is 1.2 mm thick.

How many components are on the Sensor?

13 components, from 11 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 Sensor design files?

From the kaievns/little-wing 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 Sensor design in my own project?

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