DM-73959CA-WS2812B-12RGB-BML60-D is a 3-in-1 RGB through-hole LED with an integrated WS2812B digital controller. The 12 mm diffused round package combines RGB chips, constant-current drive, signal reshaping and a precision RC oscillator in one addressable pixel.
Each pixel accepts 24-bit GRB data through a single-wire 800 Kbps NRZ interface. Regenerated data is forwarded from DOUT to the next pixel for stable cascaded lighting assemblies, while built-in PWM control provides 256 grayscale levels per color channel.
