    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.

    Good quality PCB and all necessary components are supplied to build this. Very easy to put together and worked first time connected to my Arduino.
    Please make just the PCB available for those that want to supply their own parts. Maybe consider a smaller PCB footprint that is just as big as the display with connectors as discussed above
    Good product at a good price.
  • As Said, Great Watch - Terrible Strap

    posted by liamandagnieszk

    Very cool designEasy enough to set the time and dateHuge WoW factor
    If you've been considering this watch but have been put off by some of the reviews please don't be. It is a very very cool looking watch in reality and in fairness the price is superb.The only drawbacks are that the wrist size of the strap is tiny, I have small-to-average wrists and it's a real struggle to get it on and off. Secondly the construction of the wristband is questionable and I wouldn't be surprised if it broke in the future, but hopefully I'm wrong and it'll have a long life.
    Bottom in is that it looks stunning in reality, the price is excellent and despite the two negative points above I'm happy I bought it.

    It is a really beautilful object, everyone ask me what it was, as it doesnt look at all as a tipical watch, it is very cool and looks great.
    It soud bring a manual for how to cut the strap and make it tighter to your arm. I did it but i imagine that for some people is not that easy to guess how to fix that
    It is a really beautifull watch, perfect for a gift or just to buy it to yourself
  • Cool Watch!!!!

    This watch looks really cool. It´s kind of big but very confortable. All my friends ask me to take a look at it, and everybody likes it. I like the purple and white color. At night, you can perfectly see the time, it even helps me some times, when my room or car is to dark, it works like a flashlight.
    Some days ago I found out that if you keep the light button pressed, the light color is going to change... it becomes red, green, pink and blue, so you can choose wich one you like the most.
    It´s a nice choice if you like to look different, wearing cool stuff... and have your friends and a bunch of people looking at your arm
