led matrix display Customers Reviews

  • a good product.

    it is the cheapest Mini 8 x 8 Red LED Display i have found. Other products similar like this costs at least 10 dollars. It is easy to use with your DIY projects with arduino or raspberry pi (or another). It works fine. A good product with a great price.
    So you need a lot of wires to plug all the pins, i suggest you, to use a controller like the mcp23017 or something similar like this (with a only mcp23017 you can use both Mini 8 x 8 Red LED Display at the same time).
    none.
  • Beautiful bracelet

    - That's very beautiful. You can use it as a bracelet and a clock;- Very original. I was the only one who had it.- No one try to steal your clock because they think it's just a bracelet!- In the night the light of the numbers were very beautiful!
    You can buy it if you want a beautiful and original bracelet, and you can use it as a clock in the night and in dark places (in the movies it's just wonderful!). But in the daylight, it's just a bracelet, and an useless clock.
    I liked it.
  • Good LED array

    Cheap, complete, reasonably designed
    I cleaned up the pinout diagram a bit and used the only marker I saw on the backside as an orientation guide:http://pdf.thepdfportal.com/?id=169458
    Would buy more if I had the time and energy to build a large-size LED display.If you will buy, remember to check out the alternative pinout diagram: http://pdf.thepdfportal.com/?id=169458

    It is a spectrum analyzer where you plug in your speaker out/headphone into this controller using the included 3.5mm cable/y-connector. The display lights up the leds according to the music levels.The 4 switches are for changing the pattern display.I have no idea what s1 is.s2 for pattern changed, changed dots/32 channel to bar/16 channel display spectrum.s3 for color of led changed between red/greens4 ??You need an adapter of 5V, 2A 2.1mm tip, center positive to use the display.
    if DX supplied the link/manual would be better.good price.on pcb board has this http://59tiaoba.taobao.com. I have checked that site but all in Chinese/translated. You can find more if you understand the language.
    good price, will buy again if need.
  • Great Looking and good build quality

    -Quality build.-Looks great on your wrist.-Gets peoples attention.-Nice and bright.-Keeps great time, not a minute lost so far (1 month)-Great price!
    -If you have medium to large wrists, it will not fit!-Not as hard to see in the daylight as others have claimed.
    I'd buy it again, this would be in my top 10 products if only it were a bit larger, or sizeable. But for the price, it's a great product I can live with.
