Overview
Keyboard is an open-source printed circuit board by ManoShu, from the ManoShu/BareDev repository on GitHub, published under the MIT licence. It is a 2-layer board of 298.5 × 127 mm with 175 parts on 116 nets, routed with 1,313 tracks and 99 vias.
It is built around the ATMEGA32U4-AU. Its parts include 7 capacitors, 4 resistors, 1 IC, 1 switch and 1 crystal. It belongs with the keyboards and input boards and the AVR (ATmega, ATtiny) boards of this library.

An open-source, QMK-compatible, ABNT2-based 70% keyboard, focusing in a smaller footprint while retaining all the functions found on a TKL (Del and arrow keys doubling as the navigational cluster)

PCB & Case
Note: this photo is of an early prototype of the case. The uploaded files has been updated to require less total area and WILL look slighty different than shown (the overall dimensions remain the same).
The case and gerber files are under production. The had been used and confirmed to work, however use them at your own risk.
QMK
The rev1 has been integrated in the main QMK repository, being able to use the online configurator to generate the firmware while also having the files on the qmk directory here in case of you don't want to update your fork (HOWEVER the files have been confirmed working on QMK 0.2.2 [check yours with qmk --version], previous versions might not have support for some of the tags in the info.json file)
VIA / VIAL
A via keymap is available allowing to use VIA to change keybindings without the need to setup QMK.
It is not integrated with the official repository yet, but the .json file required to change bindings is available on the via directory.
A VIAL-compatible keymap is also available. It is on the official repository, but in case you don't want to update, just drop the keyboard folder to your vial-qmk directory and it should also work right off the bat.

Questions
How big is the Keyboard PCB?
It measures 298.5 × 127 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Keyboard use?
175 parts, built around the ATMEGA32U4-AU. 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 ManoShu/BareDev repository on GitHub, at the commit this page was made from: the board is kicad/rev1/keyboard.kicad_pcb and its schematic kicad/rev1/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).
