E. Calebe aka Calebe94 shared his Appa, an ortholinear keyboard inspired by the Plaid and Gherkin Apls 1.1, and sporting White Alps switches plus an Arduino Pro Mini (ATMega328p) as devboard/microcontroller.

I wanted to create a keyboard to use some of the electronic components I already have. That's why I've used USB-B instead of USB-C connector, and that's why the keyboard is so tall, but I'm happy with the results since this is my first mechanical keyboard ever – Calebe94.
