    (Always connect ground first and be sure your controller can handle hot-swapping).

    I bought a couple of the 5V controllers from AliExpress myself a couple years ago to test pixels as I was getting samples of different ones from China to look into them.
    These little controllers work really well for testing to me. I did cut the connector off the end and installed three alligator clips instead since the strings I was testing had no connectors on them but it is easy enough to use the mating connector for the string and connect the alligator clips to it if necessary.
    I could have 4 strings running at a time off one 5V power supply that I had wired up to the controller and to an AC plug which I would just unplug when changing strings around.


    Pretty cheap and easy way to test.

    Im not a big fan of hot swapping Pixels because as I13 suggested, you can damage the 1st pixel in some circumstances and I have witnessed this myself with the 12v 2811 chip in the past

    Check out "parasistic powering".. If you are going to hot-plug it..


    GND, then Power, then Any logic connections..

    Sorry to sound dumb but what do you mean by hot swapping.

    No such thing as a dumb question here, we learn by asking questions

    Hot swapping means connecting and disconnecting the lights from the controller while the power is turned on

    Many thanks. I thought as much but is always better to ask.
