Anybody got a measurement on the pwm frequency for the new CL1H V4 generation P60 pills (both the Q5 and Q2 5A pills)? So far I know the older Q4 pills were ~3.15khz and whined, then there was a batch of ~90hz pills that flickered, and now it seems these have been solved? I'd hoped for something north of 25khz, then if it whines it'll be inaudible, and it won't flicker!!

I have measured them (The Q5 and Q2 pills are the same), frequency is at low right in pictures::

Thanks so much, glad to have real data!

@Dereelight: Looks like they're still a little too low to be really interesting though :( probably usable, but if it ~can~ be seen to flicker on a moving object (fan) or by moving the light (attach it to my bike), my eyes will catch it, and flicker = not acceptable.

For now, I'll stick with my Q4 3.15khz whining pill and be happy.

Newest pill frequency at 38KHz:D

No whine can be hear, and no PWM flickering even light the rotating fan.

Now we just need to know what pills he is talking about or if it is a general update.
