- SG90 is a servo motor which operates based on PWM control signals
- The servo maintains a certain angle (position) based on the width of the pulse fed in through a signal input
- Some technical specifications
- Weight: 9 g
- Dimension: 22.2 x 11.8 x 31 mm approx.
- Stall torque: 1.8 kgf·cm
- Operating speed: 0.1 s/60 degree
- Operating voltage: 4.8 V (~5V)
- PWM frequency = 50Hz
- Pin configuration: Yellow / Light Orange / White (Signal), Red / Dark Orange (+5V), Brown/Black (Ground)
Note : The pulse width in the image does not correspond to SG90, for illustration of the concept only.
