WS2815B-RGBW-4P is an integrated addressable RGBW LED pixel for compact, programmable lighting. The controller, constant-current LED driver, signal reshaping circuit and light source are combined in one 5050 SMD package. Its 32-bit rgbw control and 4 kHz refresh architecture support smooth cascaded effects in production SMT assemblies.
