Questions
How big is the Fiddler PCB?
It measures 46.8 × 72.5 mm and has 4 copper layers, 1.61 mm thick.
What parts does the Fiddler use?
124 parts, built around the ESP32-WROOM-32E, AP63203WU, TAS5805MPWP and LAN8720A-CP. 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 Fiddler KiCad files?
From the ausocean/rig repository on GitHub, at the commit this page was made from: the board is platform/kicad/fiddler/fiddler.kicad_pcb and its schematic platform/kicad/control_board/control_board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Fiddler design in my own project?
Its repository states no licence, so its author keeps all rights: ask ausocean before reusing the design.
