  • 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.
  • 4-Digit LCD High Precision PH Meter

    posted by wreibeling

    This item is really easy to use, small and compact.It is very easy to set up, all you have to do is go buy a bottle of de-ionised water from your chemist, the buffer chemicals for calibration are supplied.Very accurate and sensitive.Solid and quality construction.
    Arrived decently packaged and safely.I can't fault it, it just works ... well!!
    Cost effective and very useful.A worthwhile purchase. I would recommend getting this item.
  • Fast test ph !

    posted by tom13n

    excellent instrument for measuring ph.as effective as three times more expensive models.Fast test in 3 seconde !it is a little more accurate than the test liquid
    you need distilled water to clean it.Cell Button Battery included.at the reception, mine was already properly calibrated.:-)
    I highly recommend the purchase of this instrument because it's a big gain of time.
  • 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!!
  • Excellent Product - and accurate.

    posted by Parrotile

    Good size and good balance. The display is clear, and all the functions are easily operated with one hand. I particularly like the retractable tip capability (no holes in the pocket). Seems as accurate as the Meterman DMM I usually use.
    Nice leads, good spacious strong bag, and the batteries do last a LONG time. This can (and has) survived significant abuse, and is a really useful little meter!
    Another VERY good buy from DX - does what it's supposed to do, with some useful extras too. Seems tough and well able to survive life in the bottom of the toolbox
