There is no physical DSD output capability on ODROID boards.

I needn't DSD output at all. I just wanna know if this board can be connected to Odroid c2 and used properly?

It might be compatible theoretically. But nobody can't guarantee without real test.
Take a risk and share your test result.

Before buying it I want to know which one is better? In my mint second board es9028 is the better choice. Isn't it? Is it any difference for Odroid c2 to connect via II2s or I2s ?

Why in the map header 1 and 3 are marked with brown color?

That color means Power rails.

Without measuring the sound quality on AudioPrecision equipment(or any other audio analyzer), it is very hard to judge which one is better.

Please explain should I use pin4 MCLK?
MCLK, do not use => The DAC has an onboard clock, do not use MCLK (can I actually remove it from the connector?)

You don't need to use the MCLK if the board has its own PLL clock generator.

DAC Pin2 Odroid Pin 6
DAC Pin 3 Odroid Pin 5
DAC Pin 4 Not Connected
DAC Pin 5 Odroid Pin 1

ES9018MK2 DAC has not its own clock generator. Please explain how to сorrect connect it?
The board seller has written:
Because the ES9018 is independent of the MCK clock 100M, so only you need to enter the DATA BCK LRCK sufficient very convenient. Polished old CD DVD decoder works well. Delicate mellow, very good extension. Default with NE5532 op amp, op amp to upgrade customer can choose their own fever op amp.

Try to use the MCLK pin on C2.
Why don't you ask the question to the DAC manufacturer?

It is a popular board. The board seller has written:

Maybe, would be better connect:
DAC Pin 1 Odroid Pin 7
DAC Pin2 Odroid Pin 6
DAC Pin 3 Odroid Pin 5
DAC Pin 4 Not Connected
DAC Pin 5 Odroid Pin 1

Could you explain connected VCC (Analog/Digital Supply ) on this photo? Is it Odroid c2 pin3 that is responsible for vcc?

Do you want to feed the power to C2 via pin3 instead of the DC-jack?
We don't recommend it since it will bypass the protection circuit.
But it will be fine if you can make sure the power source is really well regulated at 4.8V~5.2V.

Can I connect the DAC it in this way?:
DAC Pin 1 Odroid Pin 7
DAC Pin2 Odroid Pin 6
DAC Pin 3 Odroid Pin 5
DAC Pin 4 Odroid MCLK pin 4 (or Not Connected)

You have to measure the MCLK and SCK signals with an oscilloscope to find what's wrong.

To work properly with ES9018MK2 DAC Odroid 2 need driver like this for Raspberry Pi !!! Who can write driver for this DAC?
https://github.com/luoyi/Rpi-ES9018K2M-DAC
See scheme of this DAC. There are now a lot of modifications this scheme. Have you new idea to make it working?

There is no dedicated driver for ES9018K2M as of yet and nobody effort to develop one for Odroid C2.

The generic I2S driver should work.
ES9023 and PCM1704 work without any additional driver.

You haven't recommended connect pin GND and pin 5v Odroid to DAC (see photo of pins ES9018MK2 ).

Doesn't work!

Why didn't you connect the Ground pins?
What is recommended input voltage on your DAC board?
It seems to be 12 Volt.

I bought the same ES9018MK2 board and test it with the latest Volumio 2 Ver 2.166 image.
It works well with our stock HiFi Shield device driver.
5Volt source is connected to the C2 and 15Volt source is connected to ES9018MK2 board.

But our HiFi Shield Plus has better frequency response and SNR while the THD performance is very similar.
So I don't recommend this ES9018MK2 DAC board if you can't modify the output OPAMP circuitry by yourself.
