The IQaudIO Pi-DAC+ audio card for the Raspberry Pi delivers outstanding sonic performance and full-HDaudio capability with build-in hardware volume control.
The Pi-DAC+ also includes a high quality audiophile headphone amp. The Pi-DAC+ is a fully compliant Raspberry Pi HAT (A+/B+/2) board with configuration EEPROM and both camera and screen PCB cut outs. It uses the Raspberry Pi’s I2S digital audio signals delivering much lower CPU usage vs. USB audio cards. No soldering is required.
Please note : The Pi-DAC+ is compatible with Raspberry Pi 3, 2, B+ & A+
The IQaudIO Pi-DAC+ is a fully built and tested Raspberry Pi HAT, designed and made in the UK.
Output from the Pi-DAC+ is by industry standard Phono connectors (variable to 2v RMS) allowing easy connection to your existing Hi-Fi or sound system, headphone connection is by standard 3.5mm jack socket.
The Pi-DAC+ also provides access to the majority of the Raspberry Pi I/O signals allowing flexibility to your project and easy connection to our other IQaudIO products. This allows for additional peripherals (buttons, LEDs, LCDs, rotary encoders, IR sensors or similar) to be added.
Audio pin headers are also included to connect to the Full-HD 2x20w Class D Pi-AMP+.
Use raw Linux, Volumio, RuneAudio, SqueezePlug, PiCorePlayer, PiMusicBox, AirplaySync, MDP or similar and listen to internet radio, your own digital music library, or streaming music services such as Spotify – all in magnificent audio quality. The IQaudIO Pi-DAC+ easily supports 24-bit / 192kHz file formats but is equally at home with lower quality MP3s bringing your music alive sonically.

Jargon buster
Plain-language definitions for the technical terms used above.
- DAC
- A digital-to-analogue converter turns numbers from the microcontroller into a real analogue voltage. It matters if you want to generate simple waveforms, audio-style signals, or variable control voltages rather than just on/off outputs.
- EEPROM
- A type of non-volatile memory that keeps stored data even when power is turned off. In a sensor module, it can be used to store settings or calibration data so they do not need to be re-entered every time.
- ESD protection
- ESD protection helps protect electronics from damage caused by static electricity discharges. It is useful on development boards because cables, sensors and modules are often plugged and unplugged during prototyping.
- Headers
- Rows of metal pins used to plug a module into a breadboard or connect it with jumper wires. Pre-soldered headers make the module easier to use straight away without needing to solder the pins yourself.
- I2S
- I2S is a digital audio interface used to send sound data between chips, such as from a microcontroller to an audio amplifier or DAC. It matters if your project needs cleaner digital audio output than a basic buzzer or PWM signal can provide.
- PCB
- A printed circuit board is a rigid board with copper tracks that connect electronic parts without loose wires. For this kit, the PCBs also form the airplane shape, so they are both the circuit base and part of the finished model.
- RMS
- RMS is a way of describing the effective level of an AC signal, such as an audio output voltage. It helps compare audio output levels more meaningfully than a peak voltage number.
