It is a tiny and lightweight servo motor with high output power. This servo can rotate approximately 180 degrees (90 in each direction) and works just like the standard kinds but is smaller. SG90 micro servo motor can be used for remote control helicopters, micro robot, robot arm and boats. Fit for all kind of R/C Toys and can also make electronics DIY based on Arduino ,Raspberry Pi.
Interface Type: The SG90 has 3 wire interfaces in which the connections should be made as follows: Red wire-5V, Brown Wire-Ground, Yellow wire-digital pin 9
No load operation speed: 0.12 seconds / 60 degrees (4.8V)
Rotary Angle: 180°.
Stall Torque (4.8V): 17.5oz /in (1kg/cm).
Dead bandwidth: 5usec.
Operating voltage: 3.5V~6V
Program for SG90: Analog controller. You can build the project like “Robot Arm/ Robot hand/ control the servo with potentiometer/ multi servo control and so on.
