HI thanks for the reply,
i was looking at the Arduino Due ---> 168 PWM width control at 500 kHz. it is a 32 bit 84Mhz. i wanted the pwm to be part of a variable boost converter that i am trying to figure out and learn a few things on my spare time. or if i cannot make it to the boost in a satisfactory way to reuse the board for other things also. What do you guys advice.
