- order
- RGB
- brightness bits
- 8
- pwm frequency
- 2.0kHz
- pwm frequency notes
- 2kHz according to datasheet
Electrical
- led voltage
- 12V
- led voltage notes
- Datasheet 9.5-13.5V range
- vcc voltage
- 5V
- vcc voltage notes
- Internal regulator drops 12V to 5V for logic. Can use external resistor to supply 5V Vdd from higher system voltage
- gpio
- min
- 3.5V
- min notes
- Datasheet says 0.7*VDD which would be 8.4V at 12V - this appears to be a copypaste error. Actual Vdd is internal 5V bus, so 3.5V threshold
- max
- 5V
- channel current
- 10mA
- quiescent current
- 2.1mA
- wattage
- 120mW
Datasheet
- discrepancies
- GPIO min spec of 0.7*VDD (8.4V) is incorrect - actual threshold is 3.5V based on internal 5V Vdd

Technical Notes
- 12V version allows longer cable runs with less voltage drop
- Internal regulator provides 5V logic from 12V supply
- Backup data line for fault tolerance like WS2813
- 3 internal LEDs in series for 12V operation
