Pédale Vite — Multi-FX pedalboard
Pédale Vite is a DIY multi-FX pedalboard for guitar, bass or any other electric instrument.
It is based on a Raspberry Pi 4 and uses a custom audio board.
Key features:
- A large collection of effects within a single box: distortion, chorus, flanger, delay, reverb…
- Programs containing any free combination of the above effects
- 12 footswitches to activate the programs or other functionalities
- Fast and smooth transition between programs
- Up to 3 expression pedals to drive effects like wha, volume, LFOs…
- Infinite modulation possibilities
- Free effect routing
- Designed for stage and regular transport
- Silent and accurate tuner activated with a footswitch
- Standalone, no need for any external computer
- Building is easy and simple, can be reproduced and adapted by any person without specific skill
- Free software and hardware design
- And much more…

Questions
How big is the Audio board PCB?
It measures 173 × 85 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Audio board use?
268 parts, built around the NE5532, INA103KP, CS4272-CZZ and L4931CZ33-AP. 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 Audio board KiCad files?
From the EleonoreMizo/pedalevite repository on GitHub, at the commit this page was made from: the board is doc/boards/audio-board/audio-board.kicad_pcb and its schematic doc/boards/audio-board/audio-board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Audio board design in my own project?
Its repository publishes it under the WTFPL licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
