README
README.mdtobydio - a breakout board for developing with DAC and ADC ICs
A semi-assembled board to develop with DAC and ADC from chip makers like TI. Featuring a line in and line out 3.5mm headphone jack to receive and output sound signal, pin headers to interface with microcontrollers, and awesome art.
Cost: $33.87
This is my fourth pcb ever. I developed this during my pixeldust ysws where I wanted to incorporate some audio system in my project and this is one way for me to test subsystems. I learned how to find and source parts from suppliers like DigiKey, LCSC. I also learned how to get symbols, footprints, and models to help my development process.

Questions
How big is the Tobydio PCB?
It measures 42.4 × 41 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Tobydio use?
41 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 Tobydio KiCad files?
From the tobycm/tobydio repository on GitHub, at the commit this page was made from: the board is tobydio.kicad_pcb and its schematic tobydio.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Tobydio 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).
