WS2814B from Worldsemi, in a SOP-10. 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 LED constant-current PWM output with a 20 V withstand rating and a low-level output current of 16.5 mA typical (15.5-17.5 mA). |
| 2 | OUTG | output | Green channel LED constant-current PWM output with a 20 V withstand rating and a low-level output current of 16.5 mA typical (15.5-17.5 mA). |
| 3 | OUTB | output | Blue channel LED constant-current PWM output with a 20 V withstand rating and a low-level output current of 16.5 mA typical (15.5-17.5 mA). |
| 4 | OUTW | output | White channel LED constant-current PWM output with a 20 V withstand rating and a low-level output current of 16.5 mA typical (15.5-17.5 mA). |
| 5 | GND | power_in | Signal and power ground, with VSS specified as 0 V. |
| 6 | DO | output | Cascaded data output that forwards the reshaped serial data to the next pixel, with a minimum low-level output current of 10 mA at Vo = 0.4 V. |
| 7 | GND | power_in | Signal and power ground, with VSS specified as 0 V. |
| 8 | DIN | input | Main serial data input with a 9 V withstand rating, VIH minimum of 0.7VDD and VIL maximum of 0.3VDD. |
| 9 | NC | unconnected | Empty pin (空脚) with no function given in the datasheet. |
| 10 | VDD | power_in | Logic supply; the electrical characteristics are specified for 4.5-5.5 V, while the maximum-rating table lists 3.7-5.3 V. |
