Someone need to palce trial order pls contact Mandy:sales03@witop-tech.com

WS2815 and CS8812,12V individually addressable led.
WS2815 led is electric capacity inside.

What are their specificities ?

(Jason Coon) #3

Found the datasheet for WS2815B-V3: http://www.world-semi.com/DownLoadFile/138

Looks like a 12V WS2812/WS2813 variant with capacitor built in.

(Jason Coon) #4

Not finding anything on “CS8812A” LEDs…

(Jeremy Spencer) #5

I’ve just got a strip of GS8208s, 12V version of the WS3813, the strip has capacitors for every led. It works really well with FastLED though :slight_smile:

(Kris J) #6

Newbie question: What’s the cap for? To combat voltage drop along the strip? Or for over voltage protection of the ic ?

(Kris J) #7

@Kris_J I looked at the spec sheet and the Cap is a bypass filter. =)

(Yves BAZIN) #8

If I read correctly the needed current is now 10mA instead of 60mA ? that would be great !!! on top of the failure prevention if on led burns

(Jeremy Spencer) #9

10mA at 12V…

(Jeremy Spencer) #10

I’ve been testng 12V WS2818s and 12V GS8208s… I’ll try and put a post together…

(Marc MERLIN) #11

What’s the cliff notes on it? How is it better than WS 2813?

(Yves BAZIN) #12

@Marc_MERLIN as powered with 12V it requires less current hence less voltage drop for long led strips => less injection points. If I were to make Halloween or Xmas decoration for outside I would go for these instead of the 5V ones

(Marc MERLIN) #13

12V is great, that is a very good move.

(Jeremy Spencer) #14

12V power supplies are also cheaper :slight_smile:

(Jordan Whaley) #15

Will these respond to 5v logic?

(Yves BAZIN) #16

@Jordan_Whaley yes the data signal is 5v logic

(Jeremy Spencer) #17

@Jordan_Whaley , if you’re using a 3.3v MCU you need a level shifter to shift the data to 5v. 3.3v data does not work.

(Jordan Whaley) #18

Very good. Maybe will play with these in the future for larger installations

(mandy xie) #19

@Jordan_Whaley Yes,it is OK to offer u ,maybe you can contact me at sales03@witop-tech.com in the future

@Jason_Coon CS8812 is WITOP led,it is the updated GS8208.But Built-in IC,and data sheet can be sent,pls contact Mandy:sales03@witop-tech.com
