README
README.mdMacroKeyboard
This is a small macro keyboard made with Arduino and including a few different 3d printable case options.
Logic board was created with KiCAD.
The cases are angled at 7.5 degrees to match the standard angle of a keyboard.
The logic board must be installed into the case before the switches are soldered in.
Component List:
| QTY | ITEM |
| 1 | Arduino Pro Micro |
| 4 | M1.4 5-millimeter screws |

Questions
How big is the Macro PCB?
It measures 40.2 × 95.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Macro use?
21 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 Macro KiCad files?
From the smcalister91/MacroKeyboard repository on GitHub, at the commit this page was made from: the board is KicadProjectFiles/Macro.kicad_pcb and its schematic KicadProjectFiles/Macro.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Macro 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).
