  • Great PH-meter!

    posted by metalerke666

    - adjustable- works better then my A-brand PH meter- instant readout (although wait a bit when you use it in low mineral water...)- even a mini-screwdriver to adjust it- nice housing case. So easy to store when not used.
    Together with a TDS (total dissolve solids) meter or EC meter (Electronical conductivity in µs), the must have things for your freshwater aquarium!Please recalibrate every 2 months for proper use!
    Get one here, cheaper and much better!
  • Good screen but fragile

    posted by arderk

    This is a really big screen. It is certainly good board for any ARM project. Resolution and image quality are acceptable.
    I have killed mine beyond repair cause my ITDB02 shield had 5V VCC, I did not notice this and here I have screen that initializes but goes blank after a second of work. if you see the screen is going "snow" then you can be sure it is dead ((
    I would not recommend this for everyone. Buy it and use carefully! And if you use it as designed, you will have one of the best things in your lab. I will buy another one soon. And again and again. Cause 5'' is a serious power!!
  • Muy buen tester. Recomendado!

    posted by serie2

    Muy practico para tomar mediciones rapidas, la calidad de los materiales es excelente y muy resistente, es muy fácil de usar r sobre todo trae todas las funciones de un tester convencional pero ocupa solo una minima parte del tamaño de un tester.
    Viene con los cables, el manual y la batería incluida. Para un electrónico o electricista es muy muy recomendable.
    100% recomendable como equipo y con un precio muy accesible
  • Feature-packed LCD with good software support

    posted by gigamegawatts

    This is identical to the TFT01-2.4 LCD sold by ElecFreaks. You'll find tech specs and sample code on their web site.Compatible with the awesome UTFT library, with supports Arduinos, Chipkit (PIC) and some ARM processors. Specify the S6D1121 controller (model parm ITDB24E_8).Compatible with the TFT01 Arduino shield (DX 179397) - I'm using mine with this shieldPerformance with an Arduino is surprisingly good: no noticeable lag with line graphics or large fonts.
    Based on the comments at the bottom of the page, there seems to be some confusion about whether the unit has 40 or 44 pins. Mine has 40, but is labelled "sod44pin" at the bottom. Go figure.Haven't tried the SD card socket yet.
    Amazing number of features for the price.

    + Cheep price+ Good quality+ English instructions+ Back lit clear display
    At first look it seams to be flimsy, not super.But after calibration, and getting to know the tool its quite satisfying.Just make sure to turn it of after use, because it will suck the battery dry.
    For this price, its a great product. Have a cheaper one (yellow one, that I ordered from ebay) that is a lot lower quality, this one is fairly sturdy and I'm glad for my impulse purchase.
