This macropad is built to be in the shape of the optimized compact layout for 17 squares within a larger square. It has 17 keys with rgb backlights. It uses QMK Vial to allow the keys to be customized.
PCB
There are two parts for the PCB. The main part holds the switches and the secondary small one allows the microcontroller to be attatched directly under in a more compact way.

Questions
How big is the Optimized macropad PCB?
It measures 151.1 × 87.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Optimized macropad use?
54 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 Optimized macropad KiCad files?
From the Person20020/optimized-macropad repository on GitHub, at the commit this page was made from: the board is PCB/PCB.kicad_pcb and its schematic PCB/PCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Optimized macropad design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
