how many channel you want? maybe ESP32-S3 not have enough GPIOs for PWM output.
Yes, removing the PCA9685 for the outputs and letting the ESP32 output the PWM signal which is then "amplified" by a MOSFET driver IC connected to a beefier, low Rds_ON MOSFET should work since this is exactly my current setup. If the driver IC and MOSFETs are properly chosen, it should not get warmer than 30-35 °C so no heatsink is necessary.
I created the PCB I currently use myself. It works but I'm looking for a more "industrial-grade" (e.g. din rail mountable) solution or at least something which was designed by people who are PCB experts and not hobbyists like me.
I think 10 or 16 channels per board should be fine. If someone needs more output (like me), they could buy multiple boards.
Here (https://quinled.info/quinled-an-penta-di...are-guide/) is the only board I could find which on paper should satisfy my needs but it is not available as a pre-made board. On the page I linked there is schematics and concrete component list (orderable from LCSC) which might help if you decide to design a new Kincony board for filling this market gap.
