But for the plane, i will need 4 inputs and 4 outputs. this is more than the 6 and I was planning on adding more later for more functions.
What do you want the PWM for?Servo/ESC control or direct motor speed control?If the former, just use the Servo library on any pin.
Hi, thanks for the quick reply, I will use them for the servos and escs. I have all the motors already connected to the esc'sand what is the servo library?
There are no PWM input pins on any Arduino. There are analog pins and there are pins that can output PWM.
You could try this
Maybe a good starting point would be Ardupilot
