is somewhat dubious as it lists the pixels as WS2812B (the same as Adafruit's) alongside the WS2811 in brackets... AFAIK the WS2812B and WS2811 are two different products...NeoPixel Rainbow Biscuit for Arduino / uC - 3x3 Matrix WS2812B (WS2811) Addressable RGB LED with Built-in Drivers
Anyway... The square 3x3 matrix form actually fits the CF perfectly! As you can see in this photo-
The matrix form would allow for all kinds of basic shapes and/or indication lights such as a directional arrow or even a color responsive balancer.
The problem is that even though it has fewer pixels than the 12 pixel ring, the Amazon page lists the weight at 0.2 ounces. While my metric conversion ability is admittedly lacking, I believe that converts to roughly 5.6 grams? I have read that the CF1 would have trouble with a payload of anything over 4 grams... Is this correct? Is there anyway to either increase the payload capacity or create a 3x3 LED matrix that weighs less? Has anybody else attempted other Neopixel/CF1 combinations other than the ring?
