WS2812 and strobing at 100 Hz

May I ask how can you know the maximum refreshing frequency is 400 Hz ?

Cause that is the PWM frequency of the brightness control circuity.

In future do not resurrect a year old thread. We are more than happy if you start your own, but don’t do this again.

A new wrinkle to this story about 400Hz update (PWM). There is a new version of the WS2812B that refreshes at 2000Hz:

It does sound like discrete LEDs are the way to go to get precise timing.

No it doesn’t.

These LEDs have very imprecise internal clock circuits. There is not way to get any semblance of precise synchronization.

If you want a sharp stroboscopic effect you need one control for all the LEDs.
