TowerPro SG90 Micro Servo, Arduino CompatibleDescription:This Servo Motor works well for basic servo experimentation and can be used in applications where small size is a virtue and that dont require a huge amount of torque.Gears are nylon which is the case with most lower cost Servos.Servo motors can be commanded to go to a specific position, such as for turning the front wheels on an RC model for steering or pivoting a sensor on a robotic vehicle.Key Features of SG90:Very small micro sizeCan lift 3.75 lb positioned 1 cm from center of shaftServo can rotate approximately 180 degrees (90 degree in each direction)Analog driveSpecifications:Dimensions (L x W x H) = 0.91 x 0.48 x 1.14 inch (23.0 x 12.2 x 29 mm)Weight = 0.32 ounces (9 grams)Weight with wire and connecter = 0.37 ounce (10.6 grams)Stall Torque at 4.8 volts = 22.2 oz/in (1.6 kg/cm)Operating Voltage = 4.0 to 6.0 voltsOperating Speed at 4.8 volts (no load) = 0.12 sec/ 60 degreesConnector Wire Length = 9.5 inches (24.13cm)Universal “S” type connector fits most receiversThe wire colors are: Red = battery positive, Brown = battery negative, Orange = PWM signalPackage Includes:1 SG90 Servo motor with attached 9.5″ control cable3 arms/horns for various interface applications3 screws for mounting arms to the servo and mounting the servoTowerproSG90
