The image above compares the “grandfather”, the WS2812S, with two new devices based on the SK6812 controller. The SK6812 is a direct clone of the WS2812B, while the SK6812mini comes in a smaller package with a 3.5×3.5mm² footprint. This is quite useful, since it allows more dense matrix displays than with the normal 5.0×5.0mm² packages.
