Introduction: The SG90 servo motor is a tiny and lightweight motor which can perform different angle adjustment (180° servo) or rotation control (360° servo).

The SG90 designed duty cycle (pulse length) is 500µs to 2500µs, during this range, the duty cycle will be representing different meaning.
For 180° Servo, the duty cycle will represent to the position
Duty cycle(us) Degree
500 0°
833 30°
1166 60°
1500 90°
1832 120°
2165 150°
2500 180°
For 360° Servo, the duty cycle range is different, and the meaning represents direction and speed
Duty cycle(us) Direction Speed
1000 clockwise 100%
1166 clockwise 60%
1333 clockwise 30%
1500 N/A stop
1666 anti-clockwise 30%
1832 anti-clockwise 60%
2000 anti-clockwise 100%
Determine the type of servo (180°/360°)
Look at the side that has cable pull out, checking whether there is a variable resistor or not.
If have a “green variable resistor”, that is 180° servo.
Otherwise, that is 360°
