Overview
Greek Keyboard is an open-source printed circuit board by ZackHarrington, from the ZackHarrington/PCB-Projects repository on GitHub. It is a 2-layer board of 123.3 × 100.2 mm with 160 parts on 104 nets, routed with 612 tracks and 81 vias.
It is built around the ATMEGA32U4, BAT54L and 10UF 10V, with the BSS316N among its other parts. Its parts include 43 resistors, 31 diodes, 31 switches, 9 capacitors and 2 ICs. It belongs with the keyboards and input boards and the AVR (ATmega, ATtiny) boards of this library.

Questions
How big is the Greek Keyboard PCB?
It measures 123.3 × 100.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Greek Keyboard use?
160 parts, built around the ATMEGA32U4, BAT54L, 10UF 10V and BSS316N. 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 Greek Keyboard KiCad files?
From the ZackHarrington/PCB-Projects repository on GitHub, at the commit this page was made from: the board is Greek-Keyboard/Design-Files/Greek-Keyboard/Greek-Keyboard.kicad_pcb and its schematic Greek-Keyboard/Design-Files/Greek-Keyboard/Greek-Keyboard-LEDs.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Greek Keyboard design in my own project?
Its repository states no licence, so its author keeps all rights: ask ZackHarrington before reusing the design.
