The JustBoom DAC Zero pHAT is a plug and play, high resolution, digital-to-analog converter for the Raspberry Pi Zero and is by far the easiest and neatest way to add an audio output to your Raspberry Pi Zero. The JustBoom DAC Zero pHAT has been designed with a super-compact form factor matching that of the Raspberry Pi Zero but still features a considerable amount of functionality. It will work with any version of the Raspberry Pi, but with the larger versions we recommend its bigger sibling, the JustBoom DAC HAT.

We’ve designed the JustBoom DAC Zero pHAT to be simple to install and use. With no soldering required and all the mounting hardware already provided for you this product is suitable for absolute beginners and seasoned professionals alike. Just connect your DAC Zero pHAT to a set of powered speakers, headphones or an audio amplifier and you can be up and running quickly, enjoying flawless high quality audio playback within minutes of setting up this Raspberry Pi pHAT. We also include an optional IR receiver to allow remote control operation of your Raspberry Pi.

Includes a 384kHz/32 bit DAC chip with hardware volume mixing as well as a 25mW headphone amplifier. Outputs are line level over 3.5mm jack cable and headphone amplified over 3.5mm jack cable (both stereo). There is an option for users to add line-level, stereo RCA jacks to the board as well as a playback LED should you need them. The pHAT uses the I2S interface for its audio input which reduces CPU load on the Pi Zero compared to USB solutions. It is also powered directly from the GPIO header so no extra cables or power supplies are required to connect to the Raspberry Pi.

  • Full high quality audio - 384kHz / 32bit
  • Includes both a DAC (digital to analog converter) and headphone amplifier
  • Line-level RCA and headphone amplified 3.5mm jack outputs
  • Plug and play compatibility for ease of use
  • Hardware and software volume control from your Raspberry Pi
  • No soldering required
  • Powered by the Raspberry Pi GPIO header
  • Compatible with Raspberry Pi Zero v1.3 and Wireless (and also compatible with the Raspberry Pi A+, B+, 2B and the new 3B, but we would recommend the JustBoom DAC HAT for this purpose)
  • Mounting hardware included
  • Optional IR receiver included in package
  • Full driver support in Raspbian / NOOBS
  • Compatible with the JustBoom Player / OSMC / RuneAudio / Volumio / Moode / PiCorePlayer / PiMusicBox / OpenELEC and others
  • JustBoom Player pre-configured software available on SD cards

  • Burr-Brown / Texas Instruments PCM5121 DAC chip - 384kHz / 32 bit. Please note that due to Linux driver restrictions, max frequency is currently limited to 192kHz by standard on the Raspberry Pi - however, this can be increased with some manual driver updates
  • Texas Instruments TPA6132A2 headphone amplifier - 25mW
  • Fully integrated hardware volume mixing via 'alsamixer' or any ALSA compatible application
  • Single line of code in the Raspberry Pi config to activate the device tree driver configuration (or a simple menu based setup in some operating systems)
  • Optional Vishay TSOP4838 IR receiver included (solder yourself if required) - Also possible to use Vishay TSOP4938 or TSOP4138 or TSOP34338SS1F
  • 106dB signal to noise ratio (SNR) and -92dB total harmonic distortion (THD +N at -1dB) for best-in-class audio
  • Advanced ESD protection on both headphone and RCA outputs
  • Ultra low noise voltage regulator for the best audio output (LDO 30uVrms)
  • Optional solder-yourself RCA jacks for additional stereo line-level output – Switchcraft PJRAN1X1U02X (white) and Switchcraft PJRAN1X1U03X (red)
  • Optional solder-yourself playback LED – Kingbright L-934GD (green) or Multicomp MCL034MD (red)

  • Add an audio output to your Raspberry Pi Zero in a neat and simple way
  • Streaming (either from cloud or network storage) high-definition audio player
  • Multi-room audio player
  • Media centre / set-top box living room entertainment system
  • Shop floor / elevator / background music audio player
  • High quality audio player with local storage
  • Desktop high definition audio player with amplified headphone output
  • And many many more....
