Looks like WorldSemi is upgrading WS2812 again, without changing the model number, again.

Looks like WorldSemi is upgrading WS2812 again, without changing the model number, again. This time with integrated filter capacitors, reverse polarity protection, over-voltage protection, and 3.3V logic compatibility! I’m looking forward to getting ahold of some of these. They mention in the post that their stock of the current version will likely keep shipping for about a year, though.

Thanks for the tip on Instagram, @Leon_Yuhanov ! https://www.instagram.com/p/Bq1hd1IHgyU

Updates sound good!
Having to worry about getting the old stock if you want the new stock is a pain though. :confused:

Sounds great! I still can’t believe how high the defect rate is on these things though. “<1%” is pretty bad!

@Jason_Coon i was just about to repost this here! thanks mate! These are all awesome, my concern ATM is how I’m going to guarantee that im getting these new chipsets, there is no way to identify the new from the old especially if you get your pixels custom fabbed

@Jason_Coon thanks for sharing !!! I do agree with +Marc Miller it will be difficult to know what we are buying exactly… let’s hope they have a specific ref number

@Ryan_Cush I think it is 1 °/000 not %

@Christoph_Wempe what does that actually mean?? :slight_smile:

@Ryan_Cush TIL: “permyriad (per ten thousand) sign ‱ (also known as a basis point), which indicate that a number is divided by ten thousand”

Isn’t the version number described in one of the last page? Example for 5050 it’s ws2812e-v5? Too bad I just got some ws2813…

I hope this will be available in ws2813 package, I’ve had too many strips that break at the cut point and where they keep wanting to put a hole just where the data line goes through.

@Marc_MERLIN I believe they are rolling this out ALL their pixels. HOWEVER i have not been able to confirm any of this. I have emailed them many times in the last 2 weeks and have not received a reply. Their website also has 0 mention of any of this

@Leon_Yuhanov thank you. Speaking of which, how is your high density strip/matrix project doing?

@Marc_MERLIN Ill wait until these new pixels come out, my current prototypes all have no filter caps and don’t work well unless you manually solder them on to the strip. I’ve also seen massive failure rates with these 2020 pixels.

@Leon_Yuhanov thanks for the update, good luck with the new pixels.

Curious if anyone has been able to find this new version for sale anywhere?

@marmil NOPE, Ray Wu (on AliExpress) has the new 12V ws2812 but it doesn’t look like they are the same as the strips all have caps. From my email coms with WS it seems this is something that will be rolled out slowly and for the short term only to the 5050 range.

@Leon_Yuhanov ok thank you for the info.

@marmil So i just saw this post https://www.instagram.com/p/BspggSfHoUH/ from http://tyrialight.com (FYI I have used them commercially in the past and they are NOT the best fabricator of strip) This seems to be a clone model called TY8812 that has all these new features

@Leon_Yuhanov oh interesting, thank you.
