I'm looking for a I2C PWM Expander with individual PWM Frequencies for each output of the Expander.
My plan is to run several Mosfets with different Loads and control them with this PWM Expander.
I found the Adafruit PWM Expander, but it only has a fixed Frequency for all Outputs.
My thoughts were to either group my mosfets and use the same chip as on the Adafruit Expander, cheap microcontrollers that may be able to handle this task or a specific chip that is capable of doing this.
Any recommendation is a help and appreciated! Advices on ICs would be awesome.
Thanks a lot!
