IQaudio sound cards are for all current Raspberry Pi and those that have a
40-pin GPIO header. This includes Raspberry Pi 4B 3B+, 3A+, 3, Zero etc.
Some of the products are full size HAT boards, others are more for the Raspberry Pi Zero form factor.
IQaudio sound cards have been designed for a specific purpose, that is to integrate with your existing HiFi audio or Raspberry Pi based multimedia devices. The best audio playback is provided by the DAC PRO, DAC+
and DigiAMP+ cards. All support 24bit depth and 192kHz (Full HD Audio).
IQaudio DAC+
is an AudioCard-HAT for all generations of Raspberry Pi from Raspberry Pi 1 Model B+ The sound card supports up to 24-bit 192kHz high-resolution digital audio.
DAC+ uses the Texas Instruments PCM5122 DAC to deliver analogue stereo audio to a pair of phono connectors and also supports a dedicated headphone amplifier.
Getting started
DAC+ 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.
P1: Analogue output (0-2V RMS). Carries GPIO27, MUTE signal (headphone detection), left and right audio and left and right ground.
P6: Signals from the headphone socket. Pin 1: LEFT, pin 2: GROUND, pin 3: RIGHT, pin 4: GROUND, pin 5: DETECTION.
