  • Excellent shield and very easy to use!

    posted by IronManu

    It is very easy to connect and to use. You can use the "LiquidCrystal" library of Arduino microcontrollers, so the communication with it is reduced to a simple call to an inner method.I have tested the shield with Arduino UNO and Arduino MEGA and, also, with ST Nucleo Board.It works excellent in all of them.
    Although using the same analog entry for all the buttons is complex to manipulate for a non-expert user, I think it is the best choice to let the more unused pins, so you can use the others with several sensors and so on.
    Sumarizing, if you look for an LCD display to represent your information THIS IS THE SHIELD YOU ARE LOOKING FOR, because it is very simple, very cheap and it works very well!!
  • Good product

    posted by lucaspcamargo

    This product is relatively cheap, works great, and is adorable. Perfect for those small projects centered around a single chip. Also has a nice glue pad in the bottom side. Quality is very good.
    Well, there isn't much els to say. It's just what it says on the description, and it works good. I don't know how fast will it oxidate, but i hope it's not soon. It looking like it's going to last for a while.
    If you are interested in this product, it's good, buy it. Other colors are available in DX as well, take a look at those.
  • Very awesome little amp!

    posted by martyparish

    Extremely small, yet enough power to drive TWO 3 watt speakers! Already has the wire leads, whereas other competition does not. Will run fine on 3 AAA batteries!
    Could use mounting holes, but you'll figure that out :)
    Buy at least three of them because you will love them and probably want to gift the other two out. Also, get the speakers here as well.
  • good audio quality

    posted by adjevanhethof

    - audio quality s good, no noise, hum or other artefacts- when running on 3.7v (of a li-ion cell), this unit still functions reliably and produces quite adequate audio levels- input senitivity is such that you can drive it directly from the headphone ouput of an ipod or smartphone- very low qiescent current; will run for a long time on a battery- well built, connection cables were included
    I used this little unit in combination with a bluetooth receiver (also at DX), using the li-ion battery of the bluetooth receiver to power this little amp. totgether with two proper loudspeakers, you get a low-cost wireless boombox with a really good sound quality.
    great component. at this price, there is no point to build it yourself.
  • Bought a bunch

    posted by UOWDMC

    Small, low power, modable device. I bought a dozen for students to use when they want to add non-interactive sound/music to their media-arts projects (or interactive where un-soldering and manually wiring the buttons is enough). Often a full arduino+mp3 shield is overkill!
    Will need an amplified output (eg cheap computer speaker set) unless very low volume is acceptable.
    If you need to simply add sound or music to something, this is likely a solution worth considering
