WS2812

Worldsemi · RGB LEDs(Built-In IC) · SMD5050-4P

WS2812 from Worldsemi, in a SMD5050-4P. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VDD power_in Power supply pin; the maximum-rating supply range is +3.7 V to +5.3 V, and electrical characteristics are specified at VDD = 5 V.
2 DOUT output Control data signal output that re-transmits the serial data to the next cascaded pixel, with a transmission delay (DIN to DOUT) of at most 300 ns under the stated test conditions (CL = 15 pF, RL = 10 kΩ).
3 VSS power_in Ground pin serving as both signal ground and power ground, the 0 V reference for VDD and the logic levels.
4 DIN input Control data signal input; logic high requires 0.7VDD to VDD+0.7 V and logic low requires -0.3 V to 0.7 V.
