WS2811S from Worldsemi, in a SOP-8. 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 | OUTR | output | Red channel constant-current PWM LED driver output, with a withstand voltage of 7 V. |
| 2 | OUTG | output | Green channel constant-current PWM LED driver output, with a withstand voltage of 7 V. |
| 3 | OUTB | output | Blue channel constant-current PWM LED driver output, with a withstand voltage of 7 V. |
| 4 | GND | power_in | Signal ground and power ground for the device. |
| 5 | DO | output | Serial data cascade output that retransmits the reshaped DIN data to the next cascaded device. |
| 6 | DIN | input | Serial data input; logic high requires at least 0.7 VDD and logic low must be at most 0.3 VDD. |
| 7 | NC | unconnected | Empty pin; leave floating (not connected). |
| 8 | VDD | power_in | Logic supply; maximum ratings are 3.5 V to 5.5 V, and electrical characteristics are specified for 4.5 V to 5.5 V. |
