RobG 1,892 Posted August 8, 2013 Share Posted August 8, 2013 WS2812B is the new and improved version of the WS2812 LED (a.k.a. 5050/WS2811.) For chip details and differences between WS2812, see attached. I have LED and 30LED/m, 60LED/m strip samples (no, not free ) available on Tindie.

jpnorair 340 Posted August 8, 2013 Share Posted August 8, 2013 Nice find. Apparently it is more efficient/bright than the old 2812, so that can't be bad. I want some. Quote Link to post Share on other sites
Rickta59 589 Posted August 9, 2013 Share Posted August 9, 2013 So do these actually seem brighter than the ones from the original group buy? Quote Link to post Share on other sites
RobG 1,892 Posted August 9, 2013 Author Share Posted August 9, 2013 Not a big difference, if any (they do look brighter on the picture, but I guess it's because the strip is black.) Looks like blue and green LEDs are different and they do seem just a bit brighter (at 3.6V blue and green, at 5V only green.) Then again, my eyes are pretty tired in the evening, especially after playing with strips for couple of hours roadrunner84 1 Quote Link to post Share on other sites
roadrunner84 466 Posted August 9, 2013 Share Posted August 9, 2013 I think they actually are a little brighter, the bleeding of the light is worse on the top strip Quote Link to post Share on other sites
RobG 1,892 Posted August 9, 2013 Author Share Posted August 9, 2013 Forgot to add that WS2812B strips have different connection layout, data line is in the middle (no big deal if you use wires to connect.) Quote Link to post Share on other sites
tingo 22 Posted August 13, 2013 Share Posted August 13, 2013 the 30 / 60 LEDs / m in your post versus the 15 / 30 LEDs / m on the Tindie page had me confused for a bit. Anyway, I want to play with these, so I ordered a couple. Quote Link to post Share on other sites
RobG 1,892 Posted August 13, 2013 Author Share Posted August 13, 2013 30/60 is per meter. I am selling 0.5m pieces, so they have 15/30 LEDs. Quote Link to post Share on other sites
tingo 22 Posted August 13, 2013 Share Posted August 13, 2013 Yes, as I said I was confused. :-) Quote Link to post Share on other sites
RobG 1,892 Posted September 30, 2013 Author Share Posted September 30, 2013 FYI, white strips (60/m) are now available. Quote Link to post Share on other sites
matt79 0 Posted March 4, 2014 Share Posted March 4, 2014 The WS2812 use 5 of the 6 pins (one of them is disconnected), and 2 of them are for Vdd. The WS2812B has 4 pins, so it's a little simpler. They're essentially the same chip, although according to my spec sheets, the 'protocol' timing is a little different, but the same library should be able to be used for both.

RobG 1,892 Posted March 9, 2014 Author Share Posted March 9, 2014 WS2812D, an 8mm RGB LED with integrated WS2811, will be available in my store next week. enl, spirilis and JWoodrell 3 Quote Link to post Share on other sites
RobG 1,892 Posted March 26, 2014 Author Share Posted March 26, 2014 Well, looks like after small run, WS2812D are discontinued. Too bad, they were perfect for making LED cubes. bluehash 1 Quote Link to post Share on other sites
greeeg 460 Posted March 26, 2014 Share Posted March 26, 2014 Well, looks like after small run, WS2812D are discontinued. Too bad, they were perfect for making LED cubes. Noooooo. I was going to use them to do exactly that as a future project!!! :'( Any indication as to why they were discontinued? They seem like a good idea. Quote Link to post Share on other sites
abecedarian 330 Posted March 26, 2014 Share Posted March 26, 2014 It'd be cool if they'd done these with the pins in a square instead of inline. Quote Link to post Share on other sites
