The JustBoom Amp pHAT is a high-quality audio amplifier for your Raspberry Pi Zero. It provides up to 2 x 40 W Class-D amplification with up to 192kHz/32bit digital to analogue conversion. The Amp pHAT plugs straight onto your Pi, no soldering required. This makes the setup super easy! Just connect 2 high quality speakers and an external power supply to the Amp pHAT – your are ready to experience one of the best quality audio that’s available for your Raspberry Pi.

The external power supply is required since the Amp HAT can output up to 2 x 40W ( 2 x 30 W RMS). This means the power supply should be quite beefy, minimum 15V / 65W is recommended.

All of the GPIO pins are sill accessible on the Amp HAT. This will allow you to add additional components to your project like, buttons, LEDs, sensors or anything else you might need.
