SK6812 RGBW

[Henry Schmidt]

Is there any option to use a 4color led on the M5 Stack ?

I need as a Test-Device for installations

[m5stack]

you can use SK6812 with m5stack device. and your mean was SK6812 RGB right? i never hear "SK6812 RGBW" before. are you sure this type ?

[Henry Schmidt]

its a true 4channel IC, I use this for a high power brightness, the 4. channel is the Warmwhite or cold white, now I need to set to 4 channels each LED

@m5stack They do exist and are supposed to be more efficient then RGB versions.
@Henry-Schmidt My understanding was that they were usable without the need for code changes.

The LED strips on our website are supposed to be sk6812 but only have 3 lines https://m5stack.com/collections/m5-unit/products/neopixel-rgb-leds-cable couldn't see your picture, are you saying your LED strip has 4 wires?

@henry-schmidt HEIC format is not supported please use jpg file format.

@lukasmaximus

its have still 3 wire- but 4 channels every LED, so if you counter - need to set the numbers of channels to 4 instead of 3 for RGB

I heard from my supplier that SK6812RGBW has been stopped production and updated to SC6812RGBW,SC6812RGBW quanlity is better than SK6812RGBW.
Here is SC6812RGBW led datasheet:http://www.normandled.com/upload/202102/SC6812RGBW LED Datasheet.pdf
