5 reviews for JustBoom Amp Zero pHAT for the Raspberry Pi Zero

  1. Rated 5 out of 5

    Working great for me. Simple to setup and also runs perfectly on a Raspberry Pi 2 with a stacking header on the GPIO (will not fit on a stock Pi 2 without removing the display connector or using a stacking header)

    Connected a 12V adapter and an old pair of Sony speakers.

    Working exactly as expected, a simple internet radio / podcast player that works off a single power cable.

  2. Rated 5 out of 5

    Lovely crisp clear sound, and very simple to put together with all parts supplied. Soldering on the IR diode was a little fiddly, but not significantly more than any other board of this type.

    Works very well, and is in daily usage as a web radio with a Pi zero, the JustBoom case and IR remote all paired up with a Volumio installation and driving a pair of powered speakers (which also run well without power, although without their built-in amp).

    Overall very happy with the nice little set-up, works perfectly.

    Absolutely blown away by this board, it is incredible value for money!
    I’m no stranger to HiFi or the Raspberry Pi, I wanted something for the bedroom so I can relax in there and listen to high quality music, either before sleep or to wake me up in the morning. Also for those cosy evenings in bed.

    I ordered the JustBoom Amp Zero, the Official Case and the IR Remote control.

    When it arrived I decided to use it with the Pi Zero W, assembling everything was easy and was really surprised by the quality of the product and packaging.

    I installed PiCorePlayer as I have been using Squeezebox based players for the past 5 years, everything installed correctly.

    To power the JustBoom Amp Zero I used a 15v 4amp switch mode power supply.

    I connected it to my Q Acoustic 2020i Speakers and sat back to listen, I was expecting it to sound “Okay” but nothing special, I have never been so wrong in my life. The quality blew me away! There is no distortion at all, it goes much louder than expected and the quality is stunning.

    I have what I class as a decent HiFi in the living room, consisting of a Naim XS2 amplifier, Arcam irDAC, Bowers and Wilkins speakers, all running from my Daphile (Squeezebox) server, which can play HiRes over Async USB. Which sounds incredible, but honestly I’d be happy with the JustBoom Amp Zero in the living room and save some cash!

    I’m going to buy more and fit them in other rooms for Multiroom audio and build one in to a box as a portable hifi with a Lipo battery.

    Buy it, you won’t be disappointed!

  4. Rated 5 out of 5

    A lovely little device which — apart from the trouble of soldering the header onto a pi zero — was entirely simple and straightforward and produces astonishingly good sound. I am just using it for a kitchen radio/streaming device and it’s plenty loud enough for that even when driven from a normal usb power supply.

    The only other problem I had was fitting the stack of amp and pi zero into the stylish little case. The fit was a little too tight and the case broke but that’s no reflection on the amp itself.

    Now I want to work out if I can stack one of the the touchpad controls on top.

    I had already a great experience with Pi0 and pHAT DAC. When the time to get a mediaplayer to my mum has arrived I decided to go with Pi0 and this shiny little offer from JB.
    A little DIY vain helps soldering and software setup. If you cannot do it it should be easy to find somebody with that proficiency.
    The TV and its remote the palyer was to be attached to has CEC capabilities, so LibreELEC/KODI works fine. The only thing I had to figure out is to program some buttons to handle volume control, but it has nothing to do with the amp per se. Like Dale Robins, I attached a pair of Q Acoustics 2020i and used 15V/4A power supply. I must say I am quite surprised by the sound quality of the whole system. Getting so much out of it for such a low budget is worth the time I spent with building it.
    I would like to openly thank here JB for their excellent support. Long chain of letters have been exchanged (even during weekend time) about an apparently strange behavior that finally turned out to be my ignorance and beyond that got good advices for other side questions too. Their documentation is also wonderful.
