Raspberry Pi IQaudio DAC Pro Audio Card

IQaudio DAC Pro

The high-fidelity audio HAT utilizes the Texas Instruments PCM5242 DAC to provide excellent signal-to-noise ratio and high audio quality for Raspberry Pi 1 Model B+, 2, 3, and 4. The DAC Pro supports balanced/differential output, alongside Phono/RCA line-level output. Additionally, the sound card includes a dedicated headphone amplifier.

Getting Started

The IQaudio DAC Pro connects to the 40-pin GPIO header of the Raspberry Pi 1 Model B+, Raspberry Pi 2, Raspberry Pi 3, or Raspberry Pi 4 without the need for soldering or an external power supply.

The DAC Pro sound expansion exposes two 3-pin headers (P7/P9) for use with the optional XLR board to provide a differential/balanced output, which is then accessible via XLR sockets located above the USB/Ethernet ports of the Raspberry Pi.

P1: Analog output (0-2V RMS). Carries GPIO27, mute signal (headphone detection), left and right audio, as well as left and right ground.

P6: Headphone jack signals. Pin 1: Left, Pin 2: Ground, Pin 3: Right, Pin 4: Ground, Pin 5: Detection.

P7/9: Differential output (0-4V RMS). P7: Left, P9: Right.

P10: Alternative 5V input that powers the Raspberry Pi in parallel.

IQaudio sound cards are compatible with all current Raspberry Pi models that feature a 40-pin GPIO header. This includes Raspberry Pi 4B, 3B+, 3A+, 3, Zero, and more.

Some of the products are full-sized HAT boards, while others are more suited for the Raspberry Pi Zero form factor.

IQaudio sound cards are designed for a specific purpose, to integrate into your existing HiFi audio or Raspberry Pi-based multimedia devices. The best audio playback is achieved through the DAC Pro, DAC+, and DigiAMP+.
