TowerPro SG90 9g Micro Servo Motor

The TowerPro SG90 9g Micro Servo Motor is one of the most popular mini servo motors used in electronics prototyping, robotics, RC models and educational automation projects. It is designed to provide controlled angular movement over approximately 0° to 180° using a standard PWM servo signal, making it easy to interface with Arduino boards, Raspberry Pi projects, ESP32/ESP8266 controllers, servo testers and RC receivers. Unlike a simple DC motor that spins continuously, the SG90 includes an internal motor, gear train, position feedback and control electronics. You send a PWM pulse signal from your microcontroller, and the servo moves its output shaft to the corresponding angle and holds position against light loads. This makes it very useful for applications that need repeatable movement such as camera pan-tilt brackets, small robotic arms, obstacle-avoiding robot steering, RC airplane control surfaces, model mechanisms and DIY automation linkages. The SG90 runs on 4.8V to 6V DC and uses a 3-wire connection: signal, positive supply and ground. For reliable performance, power the servo from a suitable external 5V supply when using multiple servos or mechanical loads, while keeping the servo ground common with the microcontroller ground. The compact 9g body, mounting ears and included servo horns make installation simple in lightweight assemblies. This micro servo is best suited for small-to-medium hobby mechanisms rather than heavy industrial loads. It is an excellent choice for students, makers, robotics clubs, RC enthusiasts and product prototyping teams looking for an affordable, widely supported 9g servo motor in India. In the box: 1 x TowerPro SG90 9g micro servo motor with attached 3-wire cable, and a standard accessory set of servo horns and mounting screws as typically supplied with SG90 servos.
