Cool sounds good to me!

What's the price difference?

That one costs about $500  Angel .

No idea on the price different yet. This highly depend on the component cost especially HiFi grade EC capacitor, analog power supply, low jitter master clock, and etc. Since Pine A64 is a DIY board, we currently only plan on a low costs and god performance DAC board first.

Once we have a proper linux version running, i would love to see an external I2S DAC (like hifi-berry)

Should be quite cheap to make - possibly via kickstarter so NRE costs of PCB making/assembly can be shared amoung many users.

If people are interested I'm willing to help with/do most of the hardware design.

What do ppl think ?

Regards

We already have such plan and welcome on your participation and plan to use ESS Sabre ES9023 DAC.

When I checked the ESS Technology DAC product page, the ES9023 was not listed:
http://www.esstech.com/index.php/en/prod...bile-dacs/
I did find PDF with some information:
http://www.esstech.com/files/4114/4095/2...101103.pdf
Is it being going to be discontinued?

The ES9023 DAC should be still an active product, I will check with ESS to reconfirm.

@TL, Lim

Agree low costs and god performance DAC i2s board , is pine64 project.
and ES9023 DAC sound is not too bad !

if you design ES9023 DAC i2s for pine64 you will support Volumio ?
This is Media player , boot from image file
if you can , try give Development board to Volumio or contact they

Volumio works on embedded systems , is open source .
someone is designed for Raspberry Pi ES9023 DAC support Volumio
https://volumio.org/

We are happy to provide Pine A64 board and DAC module to Volumio when ready, this will happen some time around March. Do you have the Volumio contact info?

Hello there,

few question about the supported external DAC features

Do you use integer or fractional clock dividers? I.e. would you be able to support both:

44.1 KHz - 44.1KHz, 88.2KHz, 176.4KHz, 352.8KHz and
48 KHz - 48KHz, 96KHz, 192KHz, 384KHz
audio families over I2S?

Would you be able to output DSD over the same I2S pins?
BCLK - DSD Clock
LRCLK - DATA Left
DATA - DATA Right

On the incoming I2S side - what frequencies and bit length do you support?

Can not wait to get the pine64 and plug it to the iancanada fifo/reclocking modules.

BTW could you make a small adapter board for the Euler connector to acces the I2S pins over u.fl sockets as iancanada did for the RPI GPIO?

The Pine A64 board has the master clock where RPi doesn't have, no sure whether still need the clock divider.
Current highest bit rate is 192KHz, we have not try out the 384kHz and not sure whether works.
The DSD data pump to I2S bus is software implementation and needs developers to try out. However, the ES9023 DAC don't accept DSD data and needs to convert over to PCM.
Design a small adapter for Euler I2S pins over u.fl is possible. However, this depend on collaboration and popularity.
