Product Details

1. This audio kit is designed for Raspberry Pi 3 (3B+/3B), and the X10-I2S Board is connected to Pi 3 by the USB connector. Please refer to the picture shows.
2. This kit is also fit for Raspberry Pi 4, but due to the change of Pi 4 USB port, the USB connector is invalid and you need to use a USB Type A to Type A cable to connect Raspberry Pi 4 and X10-I2S Board.
3. In short, if the kit includes a X10-I2S Board and use with Raspberry Pi 4, you need to prepare a USB Type A to Type A cable to replace the USB connector.
1. The Raspberry Pi board is not included in the packing list.
2. The Raspberry Pi doesn't support ES9028Q2M(DAC chip), but X10-I2S Board in this kit supports this function.
3. Raspberry Pi I2S doesn't support DSD format, but X10-I2S Board in this kit supports this function.

[FAQ & User Manual]
1/ See in a description "Raspberry pi doesn't support ES9028Q2M(DAC chip), if you want this function, please add X10-I2S Board, So do i really need this "optional" board or not?

Existing operating system such as volumio, Moode Audio..etc don’t have drivers to support this DAC chipset yet. That means this X20 DAC board cannot work Raspberry Pi directly. Then you will need an USB I2S interface board to make it work.

2/ [Hardware Installation] Note: you need to get a R-core transformer yourself Or you can buy one online, please refer to: X10-RTR Power Supply Unit, So for kit start working i also need to buy additional some "transformer" ? Don't understand.
We provided several kits for your option. I think you are looking the kit without power supply unit. Then I would like to suggest that you can consider the kit which including the R-core transformer.

3/ If any more questions, please refer to official website.

[Hardware Installation]
Note: you need to get a R-core transformer yourself
You can buy one online, please refer to: X10-RTR Power Supply Unit
Connect the R-core transformer to the X10-PWR board
a) Make sure all ports on terminal block are open (Turn clockwise to tighten, counter-clockwise to loosen). 
b) Insert wires into the terminal block in the correct order.
C) Tighten down the screws the wires you have inserted. Try pulling each wire out of terminal block in order to insure that they are fastened securely.

Grey - Grey : 6VAC 2.58A

Power Supply Unit 35W R-CORE transformer:

AC voltage Selector
110V : AC input voltage MUST be 110~120VAC
220V : AC input voltage MUST be 220~230VAC

a) Make sure that you know what voltage is being supplied by the power outlet before setting the voltage selector switch and before connecting the power cord.
b) To switch the selection, unplug the power cord and use a small screwdriver to slide the switch to the opposite position.


Before pressing the power button:
a) All AC output wires to the X10-PWR board are wired in the correct order.
b) The power cable from X10-PWR board to Raspberry Pi pin header are correctly connected.
c) The AC input voltage selector switch are correctly switched.


[Software Configuration]



Volumio (Version: 2.368)
Select the“PLAYBACK OPTIONS”menu, Turn off "I2S DAC" and select "xCORE-AUDIO Hi-Res 2" under“Output Device.” Then reboot and you are done.


Moode Audio Player (Version: 3.1)
Simply select the“Configure”menu, select "MPD" under "configuration settings", then select "USB audio device" under "Audio device", Then click “APPLY" and reboot.
