Hi guys,
How many Servos can I control with an arduino due? without interfering with its normale functions? and without adding any other supplementary boards?

Servo library

The Servo library supports up to 12 motors on most Arduino boards and 48 on the Arduino Mega.

Servo Library page doesn't say for the Due, does it:

Since the Due as 3.3V outputs and most servos I think need 5V control signals, some signal buffering might be needed.
The Due is also much faster than the 16MHz uC, so blink without delay style code could likely be used to create the 1 to 2mS wide pulses every 50mS (?) that a servo uses to go to and hold a position.
