Repository layout
- firmware/daisy — Daisy Seed firmware built with libDaisy and DaisySP
- firmware/esp32 — ESP32 control firmware and LittleFS web UI host
- frontend — Preact/Vite touch interface source
- hardware/boards — KiCad PCB and schematic files
- docs — repository notes and debugging write-ups
Quick start
- Review firmware/daisy/README.md for DSP build and flash steps.
- Review firmware/esp32/README.md for ESP32 build, upload, and Wi-Fi setup.
- Review frontend/README.md for local UI development.
- Open hardware/boards/daisyBoard.kicad_pro when working on hardware.
Uploading code
- Daisy Seed: build with the Daisy make targets, then enter DFU bootloader mode and run the flashing command from firmware/daisy/README.md.
- ESP32: build and upload from PlatformIO with the commands in firmware/esp32/README.md.
- Frontend UI: build the web assets and upload them to the ESP32 filesystem using the steps in frontend/README.md.
Notes
- The ESP32 serves the built frontend from its LittleFS data partition.
- The Daisy and ESP32 communicate over UART; the ESP32 exposes a small HTTP/WebSocket bridge for the UI.

Questions
How big is the DaisyBoard PCB?
It measures 100 × 100 mm and has 4 copper layers, 1.6 mm thick.
What parts does the DaisyBoard use?
142 parts, built around the OPA1652AID, MCP6002-I/SN and TF-01A. 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 DaisyBoard KiCad files?
From the levi2234/ChimeraMultiFX repository on GitHub, at the commit this page was made from: the board is hardware/boards/daisyBoard.kicad_pcb and its schematic hardware/boards/daisyBoard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the DaisyBoard 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).
