I am offering very cheap to build, high performance dac board based on ES9018K2M. The dac board is very very cheap to build. This is a all-in-one dac board. A complete digikey bom will be given for easy procurement of components. The dac board measures 210 mm x 132 mm. The pcb is a very high quality FPT tested FR4 pcb.
Rate per pcb is $20 and registered airmail shipping charge of $10.
If anyone is interested mail me. The groupbuy will be initiated only when a minimum of 50 participants take part in this groupbuy.

An externally hosted image should be here but it was not working when we last tested it.
How about now

I'm interested but a bit more info please? Is the board populated with anything or is it completely bare when I get it?How much approx for the components from Digikey? specs etc...?
Its a bare board as given in the photo, it won't cost much, all low cost components, may be most of the parts you might already have, the es9018k2m ic will cost around $20. I will include your name in the list if you are interested.

What regulators you planned to use, what is that big footprint in lower right corner ?
Only SPDIF input ?
Please give us more details.

This one is designed to use low cost parts, regulators used 317, 337, adp151. The one on the right lower corner is for connecting arduino nano microcontroller directly on the DAC board, LCD display can also be connected directly from the DAC board. It has three spdif input with three onboard spdif receivers, you can also connect i2s/DSD input

Yes I can provide the ES9018K2M pre-soldered for extra $20 provided I should have a minimum of 50 members willing to participate in the GB... Thanks

I'm interested.
I think your implementation is much better than Subbu DAC!
Can it switchs between various SPDIF and I2S signals through MCU?

You can switch between three spdif inputs or one spdif input and I2S input with automatic detection. I am thinking of closing the thread as there is no considerable interest in the GB.....thanks

you might give some time for the members to see your posting and decide themselves, there wasn't any reasonable priced diy project using es9023's biggest brother until now and those chinese stuff from ebay didn't take I2S as input only in the most expensive ones...I speak for myself though and think this is a great project so I am definitelly in if the time comes for the real GB;
and pls consider that every GB's interest is a little slow in the begining until some members receive the boards and give back their feedback, but anyway 50 pieces is not that hard to reach

I'am interested in 2 boards and 2 chips, pre-soldered.
Will there be any difference in shipping for two boards?
Thanks
