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. |
