General • Re: Can I use a Pico to drive the PWM pin of an LED driver that has a weak internal pull-up to 5V without damaging the P

Standard photo-transistor opto-isolators are often too slow for PWM use. Photo-transistors switch off slowly, 10's of microseconds perhaps. Certainly the TLP281 mentioned above is notably sluggish
