- pwm frequency
- 2.0kHz
- pwm frequency notes
- 400Hz is an old PWM spec. Newer WS2812b (post 2018) use updated IC with 2.0kHz PWM rate same as WS2813
Electrical

- channel current notes
- Datasheet states max 49mA current, but graph for 5050 package shows R=19mA, G,B=22mA. 3535 package has lower current

Datasheet
- discrepancies
- Datasheet claims max 49mA but actual is ~18-22mA per channel, Vds max of 26V is misleading - LEDs are integrated at 5V
