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
