rgb led module Customers Reviews

  • Easy to setup, but colours dont't mix up so good

    posted by HWaii

    - Easy to use, just connect to GND and some PWM-Pins- Comes complete with resistors- quite bright
    Mixing might be better if the LED-body would be diffused by itself and not clear.
    Not recommended if you need pure mixed colors. Otherwise it is a good buy for starting some RGB-project. Installing 3 resistors yourself wouldn't be that hard, but that module in quite convenient.
  • Works great

    Great colorsEasy to useGood refresh rateCompactRGB matrix can be disconnected and used separately
    Uses all arduino IO pins (actually it doesn't, there are few unused pins still available, one can rewire the shield or use an sensor shield to get them)
    This thing is great. Using the Colorduino library, anybody can quickly make this beast shine with colors and pictures. It's fast to work with, easy to setup and once you get into Colorduino library, it's very easy to make some really nice things (the example Plasma code is great).
  • Bright RGB LED

    posted by GeeJiiZet

    It's bright and all three LEDs in it can be controlled separately. For example when using Arduino, it can be directly powered from the PWM pins with no extra components. The diodes also start emitting at quite low voltages, so there is good range for adjusting the brightness of each channel.
    The module has pins labeled wrong. The ground pin (-) is correct, but the color channels are not in RGB order, but BRG. Easy enough to find out by testing. Also since the LEDs are separated from each other, you might want some diffusing element to mix the lights together.
    Want fancy color lights in your DIY project? Here you have 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
  • Arduino compatibility

    Bright RGB LEDsSimple hookupUser can control two pairs of LEDsFor Arduino use ShiftPWM library
    I was able to make this module work with Arduino using the ShiftPWM library from Elco Jacobs at http://www.elcojacobs.com/using-shiftpwm-to-control-rgb-leds-with-arduino/ . I only had one but I assume that the library will support daisy-chained modules. You will also need a robust 5v power supply, since the Arduino digital outputs don't have the required current to drive the module.
    If you don't mind experimenting a little, I think that this module is good value for the money.
