DM-73957CC-SK6812-12GRBW-BML60-D is a GRBW through-hole addressable pixel LED with an integrated SK6812 digital controller. Its 12 mm diffused round-head package combines the LED channels, constant-current drive, signal reshaping and a precision oscillator in one compact component.
The device accepts 32-bit GRBW data through a single-wire NRZ interface. Regenerated data is forwarded from the output pin to the next pixel for stable cascaded lighting assemblies, while built-in PWM control provides 256 grayscale levels per channel. Electrical and optical limits below are taken from the matched product datasheet.
