Euro tomboi is an open-source printed circuit board by Krakenpine, from the Krakenpine/Tomboi repository on GitHub. It is a 2-layer board of 215.5 × 128.5 mm with 101 parts on 95 nets, routed with 436 tracks and 1 via.
It is built around the BAT42. Its parts include 26 resistors, 10 capacitors, 10 connectors, 8 diodes and 5 ICs.
Sample player with Daisy
Very overengineered with effects and tonally playable multisampled sounds. Currently this repository includes only seven drum samples from free libraries, using raw multisamples from rompler-synth woud probably be a copyright violation, so I need to create my own for public examples.

The 73 most common of 101 parts.
It measures 215.5 × 128.5 mm and has 2 copper layers, 1.6 mm thick.
101 parts, built around the BAT42. 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 Krakenpine/Tomboi repository on GitHub, at the commit this page was made from: the board is euro-tomboi-kicad/euro-tomboi.kicad_pcb and its schematic euro-tomboi-kicad/euro-tomboi.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask Krakenpine before reusing the design.
