Overview
Kick is an open-source printed circuit board by bread-modular, from the bread-modular/bread-modular repository on GitHub, published under the MIT licence. It is a 4-layer board of 30.5 × 68.6 mm with 35 parts on 30 nets, routed with 258 tracks and 30 vias.
Its parts include 16 resistors, 7 capacitors and 4 ICs. It belongs with the audio and music boards of this library.
README
README.mdBread Modular
An open-source hardware modular synthesizer format designed to be minimalistic and cost-effective: USB-powered, breadboard-friendly, with analog/digital modules and MIDI alongside CV & Gate.
Find your starting point
- Build or explore: modules, specification, common parts.
- Set up KiCad libraries: workspace/library setup. Projects
use the shared
opt/fp-lib-table; initialization copies local submodules rather than cloning them. - Check/export/source parts: KiCad toolkit.
Canonical tools, JLCPCB utilities and skills live under
opt/kicad-tools/.
KiCad quick start
python3 -B opt/kicad-tools/kicad_tools.py --help
python3 -B opt/kicad-tools/kicad_tools.py doctor
python3 -B opt/kicad-tools/kicad_tools.py export --helpPython + installed KiCad CLI; no extra packages for core tools. Private checks,
Gerber/BOM/CPL export, native netlist helpers and read-only sourcing have
distinct requirements and safety boundaries.
Exports are not electrical/release/order approval; keep frozen module scripts
and production designs untouched. Historical opt/kicad-jlcpcb and
.agents/skills/{kicad-workflow,jlcpcb-assembly} resolve through
relative compatibility symlinks.
Agents: start with the KiCad workflow skill or assembly skill, then actual CLI help.

Project image and full feature overview
- Modular design: Just like Eurorack.
- USB-powered: It can be portable.
- Minimal design: Cost-effective.
- Modular MIDI support: Communicate between modules; CV & Gate still supported.
- Analog and digital signal paths: It’s your choice.
- Diverse built-in modules: A wide range of pre-designed modules.
- Configurable digital modules: Voice and CV using AtTiny 1616 or ESP32.
- Fully open source: Schematics, PCB designs and code.
- Ease of customization: Create modules tailored to your needs.
- No case required: Use directly on a breadboard or a simple base module.

Questions
How big is the Kick PCB?
It measures 30.5 × 68.6 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Kick use?
35 parts. 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 Kick KiCad files?
From the bread-modular/bread-modular repository on GitHub, at the commit this page was made from: the board is modules/kick/kick.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Kick design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
