Overview
Macro microcontroller is an open-source printed circuit board by Nicholas1023, from the Nicholas1023/macro-microcontroller repository on GitHub, published under the MIT licence. It is a 2-layer board of 66 × 45.7 mm with 15 parts on 22 nets, routed with 127 tracks and 4 vias.
Its parts include 4 resistors, 4 diodes, 3 switches, 2 connectors and 1 IC. It belongs with the keyboards and input boards and the RP2040 boards of this library.
README
README.mdMacro Microcontroller
A microcontroller and macropad combined in a single PCB, with GPIO pins for external connections. It can control GPIO pin output using keys or as a normal microcontroller with GPIO pins as input or output. To enable GPIO control, press and hold any key until the LEDs light up. Reset the microcontroller to return to normal mode.

Questions
How big is the Macro microcontroller PCB?
It measures 66 × 45.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Macro microcontroller use?
15 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 microcontroller KiCad files?
From the Nicholas1023/macro-microcontroller repository on GitHub, at the commit this page was made from: the board is macro-microcontroller.kicad_pcb and its schematic macro-microcontroller.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Macro microcontroller 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).
