Hi Lorien,

is it possible to buy a pcb?

Price?

Best Regards
Bruno

Lorien 2nd October 2011 07:15 PM

Yes, it's possible, just PM me with your address and I'll make a quotation for you! Price stays at 99 Euro without shipping and PayPal fees.
On the other hand, I'm recovered (fully functional I might say) so tomorrow I'll be back for work to fulfill older orders... but what a "pleasant" way the 'Universe' had to remind me that I'm alive.
Kind regards,
L

:) high quality parts, ultra low-noise PSUs, dual-layer board (with 2oz "solid" ground planes) and carefully routed signals - mainly clock ones related to audio conversions (autoruter?).

Is it a dual-layer board or a 4-layer board mentioned in the 1st post? Thanks.

In my post #92 I was sarcastic all the way, regarding XMOS reference design board... there is not such thing as 4-layer board on that card. I doubt there's 2 oz cooper thickness also. On the other hand, WaveIO PCB have 4 copper layers with inner ones of 2 oz (~ 70um) thickness as mentioned in first post.

Below are some pics of WaveIO's layers.
Top Layer:

Huh.. I've changed the resolution of pictures above... were too big.

How is the work with the revision going? Have you considered making it a multichannel output device (analogous with this reference design)?

For me, this would make a WaveIO Rev.2 move from "probable buy" to "must buy" :) Either way, your work is commendable!

Lorien 21st October 2011 09:37 AM

I'll do my best, thank you! I'm still working on WaveIO's revision (2 channels)... without any rush though, since I want to double check new parts and make layout carefully. I had an ideea about multichannel way but one step at a time: if the two channel option is "well" implemented then the multichannel one will be built on it. At least, this is my approach.
Cheers,
L

Hi folks.

Could somebody please update me if there is a multichannel I2S option with your device
that would also be running on Linux drivers?

Thx
