These are skinny addressable 1-meter-long 5V RGB LED strips that come packed with 60 SK6812s. SK6812 LEDs are very similar to WS2812s (or “NeoPixel”) and work with the same libraries! As these are bare LED strips that have no protective coating, your project won’t be water proof but there is access to each SK6812 LED and each strip length can be easily modified to fit the length you need. You will be able to control each LED RGB individually, giving you the ability to create cool lighting effects for your car or perhaps under-cabinet lighting in your kitchen!
Note: These come in 1m segments on a reel. They are preterminated with 0.1" spaced 3-pin connectors, as shown in the pictures.
