Overview
Macr0 is an open-source printed circuit board by Clewsy, from the Clewsy/macr0 repository on GitHub, published under the MIT licence. It is a 2-layer board of 44.5 × 44.5 mm with 26 parts on 48 nets, routed with 238 tracks and 13 vias.
It is built around the ATMEGA32U4. Its parts include 10 resistors, 5 switches, 4 capacitors, 2 connectors and 1 IC. It belongs with the AVR (ATmega, ATtiny) boards of this library.

README.mdmacr0
4-button HID compliant USB macro keypad.
A bunch of extra info can be found at clews.pro.
Goals for this project:
- HID compliant USB peripheral using an ATmega32U4 microcontroller.
- Keys will be mechanical Gateron switches - these are pin-compatible Cherry MX clones.
- Keys will all be LED back-lit.
- Back-light illumination will be adjustable.
- Connectivity (and power) will be via a USC-C connector, configured for USB 2.0.

Questions
How big is the Macr0 PCB?
It measures 44.5 × 44.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Macr0 use?
26 parts, built around the ATMEGA32U4. 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 Macr0 KiCad files?
From the Clewsy/macr0 repository on GitHub, at the commit this page was made from: the board is hardware/pcb/macr0.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Macr0 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).
