Overview
ModulinV2 is an open-source printed circuit board by RamsesKlap, from the RamsesKlap/FinalThesis repository on GitHub. It is a 4-layer board of 254.3 × 169.3 mm with 642 parts on 432 nets, routed with 4,043 tracks and 411 vias.
It is built around the TL072HIDR, SN74AHCT1G00DBVR-TP and TMUX4051DYYRQ1, with the CD4028BM96, L7812CD2T-TR and SN74AHC1G02DBVRQ1 among its other parts. Its parts include 219 capacitors, 169 resistors, 48 ICs, 24 diodes and 6 switches.

Questions
How big is the ModulinV2 PCB?
It measures 254.3 × 169.3 mm and has 4 copper layers, 1.6 mm thick.
What parts does the ModulinV2 use?
642 parts, built around the TL072HIDR, SN74AHCT1G00DBVR-TP, TMUX4051DYYRQ1 and CD4028BM96. 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 ModulinV2 KiCad files?
From the RamsesKlap/FinalThesis repository on GitHub, at the commit this page was made from: the board is KiCad/ModulinV2/ModulinV2.kicad_pcb and its schematic KiCad/ModulinV2/ADSR.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ModulinV2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask RamsesKlap before reusing the design.
