A simple LED Memory Game PCB with an integrated Arduino Nano
LED Memory Game Nano is an open-source printed circuit board by Aahil78, from the Aahil78/LED_Memory_Game_Nano repository on GitHub, published under the GPL-3.0 licence. It is a 2-layer board of 74.3 × 41.6 mm with 23 parts on 37 nets, routed with 88 tracks and 3 vias.
It is built around the LM340AT-5.0. Its parts include 4 resistors, 4 diodes, 4 switches, 1 IC and 1 connector. It belongs with the AVR (ATmega, ATtiny) boards of this library.
This is a simple LED Memory Game PCB that has a built-in Arduino Nano, 4 LEDs (Red, Green, Blue, Yellow), 4 Buttons, a vibration motor/buzzer, DC barel jack, 4 resistors, and that's it!

It measures 74.3 × 41.6 mm and has 2 copper layers, 1.6 mm thick.
23 parts, built around the LM340AT-5.0. 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.
From the Aahil78/LED_Memory_Game_Nano repository on GitHub, at the commit this page was made from: the board is src/LED Memory Game Nano.kicad_pcb and its schematic src/LED Memory Game Nano.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
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).
