Description
Note:
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.

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
IMPORTANT !!!(Read Me)
Connect the R-core transformer to the X10-PWR board
- Make sure all ports on terminal block are open (Turn clockwise to tighten, counter-clockwise to loosen).
- Insert wires into the terminal block in the correct order.
- 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.

IMPORTANT !!!
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.
