A10-OLinuXino-MICRO availability?
« on: December 22, 2013, 02:13:16 PM »
I read that the A20-OLinuXino-MICRO product can run with an A10 SoC (http://olimex.wordpress.com/2013/05/24/a20-olinuxino-dualcore-cortex-a7-prototypes-work-fine/) so what are your plans for releasing a "A10-OLinuXino-MICRO" product?  The A10-OLinuXino-LIME looks nice but the spec sheet doesn't say anything about it having audio I/O, both of which I need for my application.

Yes, I could go with the A20 product right now, but I don't really need all that horsepower so I'd prefer something cheaper.  And, yes, I'm evaluating the A10S-OLinuXino-MICRO too.  So please restrict answers to the question about availability - I don't need suggestions for alternatives :-)

According to the A10-OLinuXino-LIME schematics available here
- https://github.com/OLIMEX/OLINUXINO/tree/master/HARDWARE/A10-OLinuXino-LIME
analog audio in/out is available via GPIO-1 (pins 10/14/18).

I think the product page is missing some details and also pointers to needed documentation.

Good spot!  Looks like GPIO-1 is where the mic/headphone on a phone would go:-

10 MICIN1
12 VMIC
14 HPOUTL
16 HPCOM
18 HPOUTR

Your answer inspired me to look at some other bits on the schematic and I found this on GPIO-4 (for speakerphone functionality?)

13 LINEINR
15 LINEINL
6 MIC1OUTP
8 MIC1OUTN
10 MICIN2

Some pointer to documentation on how to wire this up would be helpful - there's a distinct lack of GND connections for starters!
