The description will likely fit other I2S DAC's too, as long as you make sure to match up the I2S pins properly.
Both DACs come with a power and an I2S connector with open lead ends.
- Power connector:
red = +5V0
black = GND
orange = MCLK, do not use => The DAC has an onboard clock, do not use MCLK (you can actually remove it from the connector, see picture 1)
white = DATA
red = LRCK
black = BCK
yellow = GND
Plug: 5 x female Dupont terminal connector and a 7P Dupont connector housing.
(Of course you can use something else, I happened to have these).
Prepare the connector leads
The leads are approx. 20cm, shorten them to the length you need and put a terminal connector on each of them.
Use only one terminal connector for both power GND and I2S GND!
Prepare the Dupont connector
Then put the terminals into the housing as follows (I will call their position "pin 1" to "pin 7", corresponding to the C1+ I2S pins (see picture 2):
- Pin 1: GND <==> GND (yellow from the I2S connector and black from the I2S power connector)
Pin 2: empty, not connected
Pin 3: +5V0 (printed as 3V3)<==> 5V0 (red from the DAC power connector
Pin 4: empty, not connected
Pin 5: LRLCK <==>LRCK (red from DAC I2S)
Pin 6: SCLK <==> BCK black from DAC I2S)
Pin 7: OUT <==> DATA (white from DAC I2S)
Re-check the connections, then plug it into the C1+, see picture 3.
Make sure the yellow/black lead corresponds with C1+ I2S GND, while the white lead corresponds to C1+ I2S OUT.
First, prepare your Volumio SD Card and enable the ES9023 DAC from the Settings and Playback Menu.
For this, follow the guide as published on the Volumio site:
https://volumio.org/volumio-and-the-new ... fi-shield/
The selections are exactly the same as for the HiFi shield (so pick "C1+ HiFi shield" and "ODROID-DAC")
First, prepare your RuneAudio SD Card. To enable the ES9023 DAC, you have to edit /boot/boot.ini:
Remove the hash in front of the line containing "setenv enabledac", so it looks like this:
Code: Select all
# PCM5102 audio DAC Enable/Disable # Uncomment the line below to __ENABLE__ Audio-DAC(PCM5102) setenv enabledac "enabledac"
The C1+ will recognize the ES9023 as an ODROID-DAC, don't worry, the I2S driver is compatible.
So, select ODROID-DAC from Audio output interface in the MPD menu and you're done.
