==PACKING LIST==
*1 x X400 expansion board
*4 x nylon spacers (M3 x 20mm)
*8 x nylon screws (M3 x 6mm)
*2 x jumper links
----
==QUICK START GUIDE==
*A. Fitting the expansion board
*B. Power supply
*C. Configuring Raspbian Jessie
*D. Configuring Volumio (Not support Raspberry Pi 3 temporarily)
----
===A. FITTING THE EXPANSION BOARD===
1. Push a screws up through the mounting hole on the underside of the Raspberry Pi and screw the spacer down until it is hand tight
[[File:Assembly 275p1.jpg|left|300px]]
 
2. Plugs the expansion board straight into your Raspberry Pi B+'s GPIO header and screw down
[[File:Assembly 275p2.jpg|left|300px]]
 
----
===B. Power supply===
X400 expansion board supplies the RPi with a regulated +5V through the GPIO header using a 2A poly-resettable (PTC) fuse. 
With the wide voltage input range (6~24vdc), the RPi can be powered from a wide variety of external sources such as batteries, power adapters, solar battery sources, etc. 

Recommended Power Adapter : 110~240VAC input, 18 ~ 22VDC 4A output
Dimension of input plug (Unit: mm)

===C. Configuring Raspbian Jessie===
*RASPBIAN JESSIE
<pre>
Version : March 2016
Release date : 2016-03-18
Kernel version : 4.1
</pre>
*<1> To ensure that the necessary kernel modules are loaded at boot, ensure your /boot/config.txt file has the entry below …
<code>pi@raspberrypi ~ $ sudo nano /boot/config.txt</code> 
<code>dtoverlay=iqaudio-dacplus</code> 
[[File:X400.jpg|left|300px]]
 
*<2> You must enable i2C support for the X400 to operate. On the Raspberry Pi check if you have the following file and if so delete the line containing i2c-bcm2708 and sndsoc-pcm512x.
<code>pi@raspberrypi ~ $ sudo nano /etc/modprobe.d/raspi-blacklist.conf</code> 
Delete or comment out the lines containing the text below if it exists 
<pre>
blacklist i2c-bcm2708
blacklist snd-soc-pcm512x
</pre>
*<3> To ensure that the necessary kernel modules are loaded at boot, ensure your /etc/modules file looks the same as below…
<code>pi@raspberrypi ~ $ sudo nano /etc/modules</code> 
<pre>
snd_soc_bcm2708
snd_soc_bcm2708_i2s
bcm2708_dmaengine
snd_soc_pcm512x
snd_soc_iqaudio_dac
</pre>
[[File:X4002.jpg|left|300px]]
 
*<4> Flush your filesystem changes and reboot the Raspberry Pi
<code>pi@raspberrypi ~ $ sync </code> 
<code>pi@raspberrypi ~ $ sudo reboot</code> 
*<5> Using your mouse to right click the icon of speaker and select "IQaudioDAC"
[[File:X4003.jpg|left|300px]]
 
----
===D. Configuring Volumio (Not support Raspberry Pi 3 temporarily)===
*Testing the IR remote
*<6> Installing LIRC
<code>pi@raspberrypi ~ $ sudo apt-get install lirc</code> 
*<7> Add the two lines below to /etc/modules . This will start the modules up on boot. Pin 8 bellow will be used to take the output from the IR sensor.
<code>pi@raspberrypi ~ $ sudo nano /etc/modules</code> 
<pre>
lirc_dev
lirc_rpi gpio_in_pin=17
</pre>
[[File:X4004.jpg|left|300px]]
 
*<8> Save your changes by pressing Ctrl-x then Y
*<9> If you are using 3.18.x RaspberryPi firmware you must modify one additional file for the lirc-rpi kernel extension to be loaded:
Edit your /boot/config.txt file 
<code>pi@raspberrypi ~ $ sudo nano /boot/config.txt</code> 
and add: 
<code>dtoverlay=lirc-rpi,gpio_in_pin=17</code> 
[[File:X4005.jpg|left|300px]]
