The JustBoom DAC HAT is a plug and play, high resolution, digital-to-analog converter for the Raspberry Pi. Simply stack the plug-and-play add on board (HAT) onto your Raspberry Pi A+, B+, 2B or the new 3B and it will be ready to use immediately.
Just connect your 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 Raspberry Pi HAT.
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 the DAC HAT for easy customisation of your project – add additional sensors, buttons, LEDs, rotary encoders or anything your heart desires.
Pairing the Raspberry Pi with a high quality audio card provides the perfect solution for a number of exciting projects and applications where the standard on-board audio on the Raspberry Pi simply won’t cut it. Here are some possible use cases for the JustBoom DAC HAT and your Raspberry Pi computer:
•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
