The JustBoom DAC Zero pHAT is a plug and play, high resolution, digital-to-analog converter for the Raspberry Pi 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. Need help understanding how this product works?

Eureka, Amazing sound quality from my new JustBoom Pi Zero DAC, had an issue getting the Pi Zero to connect via the header but It was my fault for not understanding, Doh :-) but the team at JustBoom jumped onboard and helped me every step of the way. Back to the DAC - The DAC looks amazing, sounds amazing, I decided I wanted a tiny DAC to position beside my living room chair and using Volumio (free open source software) I was able to have my own very small in size but big on sound DAC. The JustBoom DAC just releases my FLAC music and allows it to be more rounded and natural as the musician intended, I also bought the Pi Zero JustBoom DAC Case and it completes the whole package into a beautiful and compact design, Next I will buy a portable battery pack and turn it into a portable DAC for 1/10th of the price of the portable DAC I was originally planning on buying. Go on treat your ears to music as It should be with a JustBoom Pi Zero DAC.
