According to the schematic and the pcb, the XIAO RP2350 has a RGB LED.
But in the RGB Blink example code there is a line #define IS_RGBW true.
This seems like a contradiction.
Does anybody know, why it’s not #define IS_RGBW false?
Maybe the RGB LED forgives the extra 8 bits without pause, but the code is still misleading.
I don’t own a XIAO RP2350 yet, so I can’t test.
Hi there,
So They sent me one of these and I thought to check it out.
First you will need SUN GLASSES 
This thing is BRIGHT. So looking at the Schematic you see the signal goes thru a 1-Bit Bidirectional Voltage level Translator UM3301DA, NO inversion takes place.

Merry Christmas 
The question is, if it is RGB or RGBW.
And if it is RGB, why does the code is RGBW?
In the video because of brightness I am not able to really distinguish all the colors.
Hi there,
I didn’t get that from the post, sounded like a logic question. but whatever…
SO YES it’s an “RGBW”, and YES it is Very Bright.

Interesting.
How did you find out it’s an RGBW?
HI there,
Oh’ that is a need to know basis only, suffice to say
I got a Mole/Frank 
in Seeed Engineering…

Arise! Go Forth and Conquer 
As you can see, the example code is a fork of pico-examples/pio/ws2812/ws2812.c at master · raspberrypi/pico-examples
Just ignore the Macro.
