Product Description


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

perfect component for hi-fi self-constructionReview by MaxM
Excellent module to set up a compact Raspberry Pi based player. Just connect some speakers and you are ready to go. The price is not really cheap, but this amp is worth every cent and even large boxes can be used. (Posted on 06/01/2017)
Improve the software!Review by Bálint
The JustBoom soundcard is great (enough to power two 100w speakers), but the max2play OS is far from good... It is said to be a special OS for JustBoom, but it is not so user-friendly. I am using the soundcard for KODI or OSMC, and for that purpose it is much better to use the stock OSMC os KODI OS. The max2play OS is very slow and full of bugs..

Answer from MAX2PLAY: Thanks Bálint for your review. Could you specify your feedback in our forum? We update Max2Play all the time and your ideas help us to improve it even more, therefore precise feedback is helpful to improve Max2Play even more. (Posted on 07/12/2016)
