Beaglebone Black audio cape
I received the new Beaglebone audio cape from CircuitCo this week, and wanted to share my experience, since documentation for this board is really not very good (Edit on the 21st of June: …but getting better all the time!). Hope this will be useful for you!
The BBB Audio Cape version B1
This is a revision of the audio cape which uses far fewer components – the card looks empty – and is based on an AC3104I chip, the TLV320AIC3104. It is now, as of June 2014, starting to become available through boardzoo, though shipping from that site is ridiculously expensive even in the US!
This audio cape simply adds a DAC and an ADC to the built-in audio capabilities of the Beaglebone. This means that the resulting “sound card” is split between native Beaglebone capabilities and the add-ons chips on the cape. OK, there is a little bit more to it such as signal processing, mixing and so on, but at a high level, this is really what it is. Just so you know…
