This is done. The constructor takes bpp which can be 4 for RGBW pixels.

Reopening to address the pixel order part of the issue. How about this:

• Create a dictionary to map string based pixel order definitions to associated order tuple
• Add parameter to __init__ to allow passing this in
• Set the ORDER tuple from the dictionary using the passed in parameter as key

Ex:
pixels = neopixel.NeoPixel(board.NEOPIXEL, 1, pixel_order="RGB")

im cool w/this but rather than passing in "RGB" lets have a constant such as neopixel.RGB?

Additionally, bpp could be set based on this argument. But probably shouldn't remove bpp from __init__? (would possibly break current examples)

I'm fine with constants. So this:
pixels = neopixel.NeoPixel(board.NEOPIXEL, 1, pixel_order=neopixel.RGB)

id leave bpp but prioritize if order is defined

There's a rough draft PR. Comment on it over there. Will make lint happy and update doc examples if this seems like the right approach.

i think we can just have the RGBW = (0, 1, 2, 3) rather than index?

Good call, was over thinking it. Removed the dict.

Closing back up. Different pixel order support added by: #24
