Description

A keyboard with 84 keys, a ssd1306 mini-display, and 2 ec11 potentiometers. It has a unque look, with lots of extra keys for ex. undo, copy, paste, print, etc. You can also control the brightness and volume with the knobs (yes, i change the brightness that often). Why? i literally thought: hmm, a keyboard would look nice on my desk. And highway happened, so i actually did it!

Questions

How big is the Keyboard PCB?

It measures 349.9 × 134.6 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Keyboard use?

170 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the Keyboard KiCad files?

From the Magicninja7/dino_keyboard repository on GitHub, at the commit this page was made from: the board is pcb/keyboard.kicad_pcb and its schematic pcb/keyboard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Keyboard design in my own project?

Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
