Lights at Lowes Island
Hello,
I recently acquired some pixels that were portrayed as WS2811 pixels.
I already have WS2811 pixels and controllers for them. This is what I know. Can anyone tell me what kind of pixels these might be.
Physical - 12mm pixels, Each pixel has a control board and a chip, wires are red, green and white.
Connection - I confirmed that the input for the pixels is on the IC side (unlike the WS2811 chips that I have). White is ground (-), Red is 5VDC, Green is data.
Behavior - When connected to a WS2811 controller
Channel 1, Pixel 1, color pulsing redChannel 2, Pixel 1, color red with dim pulsing greenChannel 3, Pixel 1, color greenChannel 4, Pixel 1, color pulsing blue
Channel 5, Pixel 1, color dim blue AND Pixel 2, color dim pulsing red
Channel 6, Pixel 2, color redChannel 7, Pixel 2, color pulsing greenChannel 8, Pixel 2, color green with dim blueChannel 9, Pixel 2, color blueChannel 10, Pixel 3, color pulsing red...
[font=arial, helvetica, sans-serif]Testing - I used the diode tester on my multimeter and read these values (voltage drop, I guess)
no chip side

Green Red White
Green 0.742 1.51
Red 1.4 1.38
White 0.634 0.525

Green Red White
Green 1 1
Red 1 1.58
White 1 0.522

[font=arial, helvetica, sans-serif]OK detectives. What kind of Pixels are these? I know that they are not WS2801 because each pixel has 3 inputs and 3 outputs. Any ideas? Is there anything that I can test to determine what I have? [/font]

[font=arial, helvetica, sans-serif](I have other things, but I think that these are the most useful to help figure this out.)[/font]
