Notes
Built-in 8->12bit gamma correction! Similar to WS2815; early version booted with onboard patterns - now eliminated
Technical Notes
- Built-in 8-bit to 12-bit gamma correction for smoother fades
- Uses MPWM (multiplexed PWM) for effective 8kHz refresh rate
- Early versions had boot pattern bug - fixed in current production
- Internal 36-bit interpolation with 12-bit gamma per color channel
