WS2816B-2427 is an integrated addressable RGB LED pixel for compact, programmable lighting. The controller, constant-current LED driver, signal reshaping circuit and light source are combined in one 2427 SMD package. Its 16-bit per channel (48-bit rgb) control and 10 kHz refresh architecture support smooth cascaded effects in production SMT assemblies.
