The Just Boom Amp HAT is easily installed and immediately ready to be used. The Amp has a class D performance amplifier with 192kHz / 32-Bit-DAC built in, for a peak performance of 2 x 55 watts. The audio outputs can receive up to 14 AWG and delivers crystal clear sound of 4 or 8 ohms. The Amp requires a 2,5A power supply which also supplies the Raspberry Pi making it the only power supply necessary for the whole system.

All Raspberry Pi GPIO pins remain accessible after mounting the Amp HAT, allowing other hardware components to still be added. Even additional sensors, buttons, LED's or rotary encoders can be attached.

At a glance:

  • No soldering required
  • Easy to install and to use with Max2Play justboom plugin
  • Back-powers the Raspberry Pi over the GPIO (with full HAT compliant protection) at 2.5A so only one power supply required for the whole system.
  • Compatible with Raspberry Pi A+,B+, 2B and 3B
  • Compatible with Amp HAT Case
  • Unused GPIO pins still accessible via unpopulated extension header
  • Mounting hardware included
