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, 3B or the new 4 and it will be ready to use immediately.

Pi Supply designed the JustBoom 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 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.

Pi Supply 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 138mW headphone amplifier. 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 customization of your project - add additional sensors, buttons, LEDs, rotary encoders or anything your heart desires.
