Description

IQaudio DAC Pro is our highest-fidelity audio output HAT. It uses the Texas Instruments PCM5242 DAC to deliver outstanding signal-to-noise ratio performance from a Raspberry Pi 1 Model B+, 2, 3, and 4, and supports balanced/differential output in parallel to phono/RCA line level output. It also includes a dedicated headphone amplifier.

IQaudio DAC Pro connects to the 40-pin GPIO header of Raspberry Pi 1 Model B+, Raspberry Pi 2, Raspberry Pi 3, or Raspberry Pi 4 with no need for soldering or external power. DAC Pro exposes two 3-pin headers (P7/P9) used by the optional XLR board to provide differential/balanced output exposed by XLR sockets above Raspberry Pi’s USB/Ethernet ports.

GPIO usage / Pin headers)

The IQaudio range of sound cards for the Raspberry Pi take advantage of a number of Pi signals in order to operate successfully. Some of these signals are solely for the use of the IQaudio board and some can be shared with other peripherals, sensors, etc. The information below covers the general cases. For more Raspberry Pi GPIO information please see the excellent site: https://pinout.xyz
We expect the following Raspberry Pi GPIO to be used by IQaudio audio boards:

  • ALL POWER PINS
  • ALL GROUND PINS
  • GPIO 2/3 (I2C)
  • GPIO 18/19/20/21 (I2S)

If appropriate then the following are also used

  • GPIO 22 (DigiAMP+ mute / unmute support)
  • GPIO 23/24 for Rotary Encoder (physical volume control) or status LED (Codec Zero)
  • GPIO 25 for the IR Sensor.
  • GPIO 27 for the Rotary Encoder push switch / Code Zero switch

Note

IQaudio DAC Pro will remain in production until at least January 2026
