JustBoom DAC HAT for the Raspberry Pi
| SKU: | 812 |
JustBoom has designed the Raspberry Pi DAC HAT to be simple to install and use. With no soldering required and all the mounting hardware already provided this product is suitable for absolute beginners and seasoned professionals alike. Just connect your Raspberry Pi DAC HAT to a set of powered speakers or an audio amplifier and you can be up and running quickly, enjoying flawless high quality audio playback within minutes of unboxing this. Also included is 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 138mW headphone amplifier (note that the Raspberry Pi is only capable of a 192kHz/32bit output). Outputs are line level over RCA and headphone amplified over 3.5mm jack cable. The HAT uses the I2S interface for its audio input which reduces CPU load on the Raspberry Pi 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. All of the Raspberry Pi GPIO pins are still accessible on our Raspberry Pi DAC HAT for easy customisation of your project – add additional sensors, buttons, LEDs, rotary encoders or anything your heart desires.

Great buy
I just bought this to add to my PI3 in my garage I am using it to stream Roon through a cheap USB Alsa DAC to Edifier powered speakers. I always thought “this is a garage set up with inexpensive speakers so it’s not worth putting a HAT Dac” well, I was so wrong! You would not believe the difference this DAC has made even with average speakers! Clarity has doubled and tighter base. Totally worth it for the price. I will bring it inside the house setup and compare it to Allo Boss DAC and I’m sure it will not hold its own.
