==Overview==
This is a redesigned X400 audio expansion board. We have adopted a lot of customer feedback on the previous version. We have made many improvements based on the previous version. I believe you will like it.
[[File:X400-V30-W800.jpg|X400 V3.0 DAC+AMP Expansion Board]]
==Features==
* Full-HD audio – up to 24-bit/192kHz playback

* Built in High quality Class-D stereo audio amplifier (TI TPA3118D2)
* Up to 2×30W Into a 8-Ω BTL Load at 24Vdc
* Capable of driving 4 Ohm speakers (also works with higher impedance speakers)
* Built in high quality audio headphone amplifier (TI TPA6133A)
* Uses the Texas Instruments ultra-low-noise voltage regulator (output noise< 10μVRMS)
* Uses the Texas Instruments high efficiency step-Down DC converter (up to 95%)
* 6V~26Vdc converted to 5.1V, 3A to power the Raspberry Pi
* Uses the genuine ALPS RK163 series potentiometer for smooth volume adjustment
* Built in high quality IR sensor (Vishay -the world's leading supplier of infrared receivers)
* Onboard RCA connectors
* Onboard 3.5mm stereo headphone jack
* Onboard speaker & power screw terminals
* <span style="color:red;">Onboard 4pin PH2.0 connector allowing to connect a external lighted power switch to control power</span>
* Onboard gold-plated high-current DC power jack (5.5x2.5mm)
* Uses the digital I2S audio signals to reduce CPU load over USB audio solutions
* Connects directly to the Raspberry Pi - No wiring required
* Powers the Raspberry Pi - no additional power supply
* Reserved Raspberry Pi GPIO pin header (2x13Pins)
* Pop-noise can be improved by enabling GPIO control
* AMP can be enabled / disabled with jumper link
<span style="color:red;">'''WARNING:''' </span>
<span style="color:red;">DO NOT APPLY POWER TO YOUR RASPBERRY PI VIA THE PI's MICRO USB SOCKET. </span>

==Hardware and Software Configuration==
More Hardware and Software Configuration please refer to [http://www.suptronics.com/miniPCkits/x400_v3.0.html web site]
===For Volumio===
DAC Model： Please choose ST400 or IQAUIDO-dac
===FAQ===
1. Why my headphone left channel has no sound?
Customer Feedback:
I am having a problem with the headphone left channel.
The sound is out of phase; the voice of the signer is almost missing on the left channel when I am using headphones.
Answer: If you happen to meet this problem, please just contact us by email and attach order number, and we will help you send a headphone cable to solve this problem.
2. Can X400 v3.0 board can be used on Raspberry Pi Zero W or Raspberry Pi Zero?
Answer: Theoretically speaking it will be compatible, but not actually it is tested, so we can not confirm.
3. Why the power switch isn't working? The LED is always green but doesn't function. When I put the power on, the Raspberry Pi is booting regardless of whether the button is on or off.
Answer: There is a jumper cap on the PWR (on the X400 board beside the 3.5mm jack headphone), when using an external power switch to control power on/off, please remove the jumper cap. Please refer to the following picture.
[[File:X400 board PWR.jpg|700px|]]
4. Which DAC model do I set with piCoreplayer?
Plase choose the '''iqaudio-DAC''' .
5.Can I have my phone charging at the same time as I have it attached to the rca playing music, or will that fry the system?
Please do not use X400 or rasdpberry pi to charge your phone, it is not support to charge the phone.
