Overview
Macropad is an open-source printed circuit board by loganw023, from the loganw023/wheatpad repository on GitHub. It is a 2-layer board of 82 × 54.8 mm with 9 parts on 14 nets, routed with 88 tracks and 12 vias.
Its parts include 7 switches, 1 IC and 1 connector. It belongs with the keyboards and input boards and the RP2040 boards of this library.
README

This is a macropad for personal use. It has six keys, a rotary encoder with a switch, and an OLED screen. I used KMK firmware to code the macropad. I used the macropad as an introduction to PCB design and to increase my CAD experience.

CAD
I used Fusion360 to create my macropad case. There are two parts: a bottom and a top. In the physical model, the PCB will be moved up to allow enough space for keycaps to be pressed.

Questions
How big is the Macropad PCB?
It measures 82 × 54.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Macropad use?
9 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 Macropad KiCad files?
From the loganw023/wheatpad repository on GitHub, at the commit this page was made from: the board is PCB/macropad.kicad_pcb and its schematic PCB/macropad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Macropad design in my own project?
Its repository states no licence, so its author keeps all rights: ask loganw023 before reusing the design.
