Frequently Asked Questions

Which Raspberry Pi models are compatible with the X400 V3.0?

The X400 V3.0 is specifically designed for compatibility with the Raspberry Pi 3 Model B+ and Raspberry Pi 3 Model B. It utilizes the standard 40-pin GPIO header for I2S audio and power, ensuring seamless integration for high-quality audio projects with these Raspberry Pi versions.

What kind of power supply is recommended for the X400 V3.0?

The X400 V3.0 operates within a broad 6V to 26V DC input range. For optimal performance, especially when utilizing the 2x30W amplifier, a stable power supply between 19V and 24V DC with sufficient current capacity (e.g., 3-4A) is highly recommended to drive speakers effectively.

How do I control the amplifier and audio features on the X400 V3.0?

The X400 V3.0 utilizes the Raspberry Pi's I2S interface for digital audio. Software control typically involves configuring the Raspberry Pi's operating system (e.g., Raspberry Pi OS) to use the correct sound card driver. The amplifier mute function can be controlled via GPIO22, and volume is managed through standard ALSA/PulseAudio utilities.

Can I use external speakers with the X400 V3.0?

Yes, the X400 V3.0 features an integrated Class-D stereo amplifier (TI TPA3118D2) capable of driving passive speakers. It is optimized for 8-Ohm speakers but can also work with 4-Ohm or higher impedance speakers. Ensure the speakers' power handling matches the amplifier's output to prevent damage.
