Overview
Macro kb is an open-source printed circuit board by joaofbmaia, from the joaofbmaia/6macro repository on GitHub. It is a 2-layer board of 68.3 × 49.2 mm with 53 parts on 50 nets, routed with 659 tracks and 67 vias.
It is built around the ATMEGA32U2-MU, SK6805E-J and WS2812B. Its parts include 17 capacitors, 16 diodes, 5 resistors, 1 IC and 1 switch. It belongs with the keyboards and input boards and the AVR (ATmega, ATtiny) boards of this library.

README
README.md6macro
This is my first attempt at designing a keyboard. Is consists of a 6-key board intended for macros or as a dedicated controller for games with few bindings such as OSU.
RGB lighting is supported and the whole build is powered by an ATmega32U2 with the QMK firmware. The 6 switches are PCB-mounted.
The case is still a WIP and is built with stacked layers of laser-cut acrylic and a top layer of decorative aluminum.

Questions
How big is the Macro kb PCB?
It measures 68.3 × 49.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Macro kb use?
53 parts, built around the ATMEGA32U2-MU, SK6805E-J and WS2812B. 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 Macro kb KiCad files?
From the joaofbmaia/6macro repository on GitHub, at the commit this page was made from: the board is macro-kb.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Macro kb design in my own project?
Its repository states no licence, so its author keeps all rights: ask joaofbmaia before reusing the design.
