Title: UEXT Module for sound
Post by: fgouland on July 13, 2013, 03:52:12 PM
Hi,

I plan to try to use your future IMX233-OlinuXino Nano as wifi sound transmitter, probably using your MOD-WIFI-RTL8188.

I need a sound input/output for microphone/instrument and monitoring headphone.

It would be nice to use an UEXT module containing a sound codec. As an example, the TI TL320AIC23B could be a candidate to become the heart of this small module. It is I2C driven and transmits with SPI. It can be powered with 3.3V.

Thank your for reading me
Regards

Jean-Louis

I'd like a hi-end UEXT sound module.
With mixer-level stereo line out (RCA + 3.5 jack), at least 120db SNR and very low THD.
Replaceable (socketed) opamps would be nice. :)

Hello,

I've just noticed that iMX233 has built-in sound input/output. They will probably be accessible on the future OLinuxXino Nano.

Maybe it will be enough to do the job : Mic/instrument or line input and headphone output...
