Notes
APA102 Clone. Extra 5 bits uses constant current driver, no change in PWM.
Technical Notes
- APA102 protocol compatible clone with improved brightness control
- 5-bit brightness uses current control instead of APA102's PWM - no 400Hz flicker
- Better for video/photography applications due to no low-frequency PWM
