Overview
Microcontroller is an open-source printed circuit board by manpreet-singh, from the manpreet-singh/Atlas repository on GitHub, published under the GPL-3.0 licence. It is a 2-layer board with 26 parts on 59 nets, routed with 96 tracks and 40 vias.
It is built around the ATMEGA328P-AU, CP2104EK and AMS1117-3.3. Its parts include 9 resistors, 6 capacitors, 4 diodes, 3 ICs and 1 connector. It belongs with the robots and motor control boards and the AVR (ATmega, ATtiny) boards of this library.

Questions
What parts does the Microcontroller use?
26 parts, built around the ATMEGA328P-AU, CP2104EK and AMS1117-3.3. 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 Microcontroller KiCad files?
From the manpreet-singh/Atlas repository on GitHub, at the commit this page was made from: the board is cad/electronics/AtlasPD/Microcontroller.kicad_pcb and its schematic cad/electronics/AtlasPD/5V Buck Converter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Microcontroller design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
