A Kosmo oscillator module that uses the Electric Druid VCDO chip.
VCDO is an open-source printed circuit board by Sonosus, from the Sonosus/VCDO repository on GitHub, published under the CC-BY-SA-4.0 licence. It is a 2-layer board of 98 × 98 mm with 93 parts on 61 nets, routed with 579 tracks and 46 vias.
It is built around the TL072, L7805 and L7905. Its parts include 36 resistors, 19 capacitors, 8 diodes, 6 ICs and 1 transistor.
This is a voltage controlled digital wavetable oscillator based around the Electric Druid VCDO1(PIC16F1847) microcontroller chip.

It measures 98 × 98 mm and has 2 copper layers, 1.6 mm thick.
93 parts, built around the TL072, L7805 and L7905. 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 Sonosus/VCDO repository on GitHub, at the commit this page was made from: the board is VCDO.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the CC-BY-SA-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
