Overview

The Raspberry Pi has an on-board audio jack, which is super handy for all kinds of sound effects and speech, just plug and go! However, for when you want better audio for music playback,This X350 USB audio card can greatly improve the sound quality and volume.

You can DIY a external speaker using the 4pin speaker cable (you can found cable in the package box), and control the speaker via the on-board button.

In additonal, you can use it on the desktop computer, you only use one USB cable to connect the desktop computer and X350, and insert earphone into the X350, then you can enjoy the high quality sound.

FAQ

1.Is it possible to use both the onboard microphone and an external microphone at the same time (2 audio input channels at the same time)?

Answer: Sorry, it is not possible to use both the onboard microphone and an external microphone at the same time, but if you need to use two microphone, you can consider to use two X350 audio board to stack on and under your raspberry pi to use it.(actually we do not test it, you need to test it yourself, thank you!)

This does not explain how to connect the 5vdc power to the card. Do you use a cable from the raspberry pi's power or do you need an independent power supply? what kind of cable is required for the power supply? What plugs in to the USB connector, is it power supply, if not the headphones or mic. If it is power supply why is there another power supply input connector?

Hello, The X350 and Raspberry Pi is connected by the USB bridge, does not require external power supply for X350, and we upload the X350 board diagram above, please check the details. Best regards, Cindy/Geekworm
