CASIO VX4 YM2413 Soundcard v1.1 is an open-source printed circuit board by hwreverse, from the hwreverse/PokeConSound repository on GitHub, published under the MIT licence. It is a 2-layer board of 46.7 × 40.9 mm with 22 parts on 30 nets, routed with 211 tracks and 23 vias.
It is built around the LMC660CM and PJ-320B. Its parts include 7 capacitors, 6 resistors, 2 ICs, 2 connectors and 1 inductor. It belongs with the retro computing and games boards of this library.


Make sure that PCBs are fabricated in 0.8mm thickness, otherwise you couldn't fit the PCB in the 2x15 1.27mm Casio Interface Connector

It measures 46.7 × 40.9 mm and has 2 copper layers, 0.8 mm thick.
22 parts, built around the LMC660CM and PJ-320B. 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 hwreverse/PokeConSound repository on GitHub, at the commit this page was made from: the board is Orig.Designs/CASIO VX4 YM2413 Soundcard v1.1/CASIO VX4 YM2413 Soundcard v1.1.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
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).
