Overview
No fi delay is an open-source printed circuit board by Krakenpine, from the Krakenpine/krakenpine-synthing repository on GitHub. It is a 2-layer board of 211.5 × 199.5 mm with 98 parts on 85 nets, routed with 366 tracks and 6 vias.
It is built around the TL072 and BAT42. Its parts include 34 resistors, 15 diodes, 11 capacitors, 7 connectors and 3 ICs. It belongs with the audio and music boards and the AVR (ATmega, ATtiny) boards of this library.
Main components
2README
no-fi-delay/README.mdNo-fi delay v1.0
Very low fidelity delay module in Kosmo format. Uses Arduino Nano 328P version with 2 kB ram. Install Mozzi library in Arduino IDE to use this. Files in KiCad format with schematic as pdf. Jack pcb and main pcb are connected with a 10 pin flat cable, like the one powering eurorack/kosmo modules. Don't accidentally connect power to that connector, otherwise this should be quite straightforward if you have build anything previously.

Questions
How big is the No fi delay PCB?
It measures 211.5 × 199.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the No fi delay use?
98 parts, built around the TL072 and 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.
Where can I download the No fi delay KiCad files?
From the Krakenpine/krakenpine-synthing repository on GitHub, at the commit this page was made from: the board is no-fi-delay/no-fi-delay.kicad_pcb and its schematic dual-vca-kosmo/dual-vca-kosmo.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the No fi delay design in my own project?
Its repository states no licence, so its author keeps all rights: ask Krakenpine before reusing the design.
