Questions
How big is the Mini dexed PCB?
It measures 100 × 75 mm and has 2 copper layers, 0.8 mm thick.
What parts does the Mini dexed use?
65 parts, built around the PAM8406DR, TPS613222ADBV, PCM5102APW and AO3401A. 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 Mini dexed KiCad files?
From the McbeEringi/pcb-stuff repository on GitHub, at the commit this page was made from: the board is proj/audio/mini-dexed/mini-dexed.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Mini dexed 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).
