- Individually addressable RGB pixel; cheap and everywhere
- backup data line
- No
- brightness bits
- 8
- channel current
- 18.5mA
- channel current notes
- Datasheet states max 49mA current, but graph for 5050 package shows R=19mA, G,B=22mA. 3535 package has lower current
- clocked
- No

- GRB
- data bitrate
- 800kHz
- data type
- WS2811/12
- datasheet discrepancies
- Datasheet claims max 49mA but actual is ~18-22mA per channel, Vds max of 26V is misleading - LEDs are integrated at 5V
- gpio max
- 5V
- gpio min
- 3.0V
- led voltage
- 5V
- led voltage notes
- Datasheet claims "26V Vds, Max" but LEDs are built-in and share power with 5V VDD
- max pixels per string

- 33.3 k Pixel / s
- 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
- quiescent current

- release year
- 2012
- spec update year
- 2018
- technical notes
- PWM frequency updated from 400Hz to 2.0kHz in 2018 silicon revision, Datasheet max current (49mA) differs from actual measured values (19-22mA), Available in many package sizes with varying current specs
