Audio Adaptor Shield REVD Kicad Symbol and Footrpint

[bmo]

Hi everyone,

I spent some time making a REVD audio adapter footprint and symbol for kicad.

I'm still pending boards made with them, but I have done a printer test and everything seems good. Let me know if you see anything that seems off and I'll make changes and re-upload here

Please feel free to use them!
happy holidays!

I added a link to this page from the audio shield page, under "Schematic, Rev D".

Hopefully it will help others using Kicad.

This is very helpful, thank you! I understand that the 2 GND connections on the audio shield are intended to separate digital ground and analog ground. Does anyone happen to know which is which? I didn't see that info on the product page.

I'm pretty sure there's only one ground on the audio adapter. The SGTL grounds are normally star grounded together to a single ground plane - at least that's the datasheet recommendation.

(Well to be precise there is a separate headphone analog ground, but its at a different DC potential and only for headphones).
