Datasheets disagree

The sources we hold state different values for the facts below. Rather than pick one quietly, both sides are listed with where each was read. Check the datasheet for the exact part number and revision you are buying. How this is shown.

Protocol SK6812 RGBW

Supply voltage

The 2015 RGBW sheet gives a lower minimum supply than later OPSCO RGBW sheets.

What each source says about supply voltage
SourceSaysPage
sk6812rgbw VDD +3.5 to +5.5 V 4
skc6812rgbw-c5378724 VDD 3.7 to 5.5 V 8

What we show. 3.7 V (the newer sheet) is shown because it is the safer minimum.

PWM frequency

PWM frequency differs between the 2015 RGBW sheet and the SKC6812RGBW sheet.

What each source says about pwm frequency
SourceSaysPage
sk6812rgbw 1.2 kHz 4
skc6812rgbw-c5378724 4.0 kHz 8

What we show. 1.2 kHz is shown, from the sheet the timing set is read from.

A 3.7 x 3.5 x 1.9 mm six-pad RGBW: three pads down each side, pin 1 (NC) top-left, then GND, DIN down the left, and VDD, DOUT, VDD back up the right. Pins 4 and 6 are both VDD. A compact way to get a dedicated white die.

Compatibility

  • protocol compatible SK6812

    Identical timing, but four channels rather than three. Driving it with an RGB library shifts colours down the strip, because every pixel consumes one extra byte.

  • protocol compatible of this Inolux PI RGBW (single-trace IC, 32 bit)

    Frame layout only: 32 bit, G R B W, MSB first, one wire, which is the layout the sk6812-rgbw protocol records. The typical T1H here is 750 ns (640 on the PI33QB sheet), not the 600 ns of the SK6812 rev. 02 table. The Inolux sheets never name SK6812.

Dating evidence

Nobody announces these parts, so this records what we can actually cite rather than a release date. Library support proves only that the part existed by that date.
