README
README.mdxiao_codec
Audio codec shield for the Seeed xiao-ble (https://wiki.seeedstudio.com/XIAO_BLE/). The audio codec is a AIC3254 (https://www.ti.com/product/TLV320AIC3254).
audio IO
The shield has header pins that directly connects to the audio IO pins of the codec. For connecting to headphones or analog microphones see the application note of the codec (https://www.ti.com/lit/ug/slau497a/slau497a.pdf?ts=1724654493899&ref_url=https%253A%252F%252Fwww.google.com%252F). I.e. if you want to drive headphones, place series capacitors (47u) on the headphone pins to remove the DC.

Questions
How big is the Xiao codec PCB?
It measures 17.8 × 21 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Xiao codec use?
9 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 Xiao codec KiCad files?
From the bliep/xiao_codec repository on GitHub, at the commit this page was made from: the board is hardware/xiao_codec.kicad_pcb and its schematic hardware/xiao_codec.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Xiao codec 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).
