Overview
Higgs is an open-source printed circuit board by lukasnee, from the lukasnee/fibration repository on GitHub, published under the GPL-3.0 licence. It is a 2-layer board with 2 parts on 5 nets.
It is built around the V7803-500. Its parts include 1 capacitor and 1 IC. It belongs with the audio and music boards of this library.

Potential Applications
- Eurorack module
- Effect pedal
Features and Technical Highlights
- Written in C++
- Currently focused on STM32F303 microcontroller
- RTOS driven (FreeRTOS + ccp_freertos wrappers),
- I2S+DMA driven audio input/output
- Hardware FPU and CMSIS-DSP utilization
- CLI shell and logger over UART for experimenting and troubleshooting
What's Planned
- Hardware component drivers and abstractions: knob, slider, button, LED, rotary encoder, etc.
- STM32H7xx support
Documentation
Licenses
- GNU GPL-3.0 for software
- CERN OHL-2.0 for hardware

Questions
What parts does the Higgs use?
2 parts, built around the V7803-500. 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 Higgs KiCad files?
From the lukasnee/fibration repository on GitHub, at the commit this page was made from: the board is modules/higgs/hardware/design/higgs.kicad_pcb and its schematic modules/higgs/hardware/design/analog.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Higgs design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
