Overview
Abc lcd is an open-source printed circuit board by behind-the-moon, from the behind-the-moon/abc-lcd repository on GitHub, published under the GPL-3.0 licence. It is a 2-layer board with 39 parts on 31 nets, routed with 354 tracks and 14 vias.
It is built around the ATMEGA8A-PU, LM2596S-5.0 and LM2596S-ADJ, with the IRFZ44N among its other parts. Its parts include 13 resistors, 8 capacitors, 5 ICs, 4 connectors and 3 diodes. It belongs with the lEDs and displays boards and the AVR (ATmega, ATtiny) boards of this library.

README.mdBOOOM !!!
It worked some time, until I've decided to test shorts....
I don't recommend this project, maybe, someday I make something better.

Questions
What parts does the Abc lcd use?
39 parts, built around the ATMEGA8A-PU, LM2596S-5.0, LM2596S-ADJ and IRFZ44N. 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 Abc lcd KiCad files?
From the behind-the-moon/abc-lcd repository on GitHub, at the commit this page was made from: the board is schematic/abc-lcd/abc-lcd.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Abc lcd 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).
