The Tower Pro SG90 Servo - 9 gms Mini/Micro Servo Motor is a widely popular, ultra-lightweight micro servo motor designed for small robotics, RC aircraft, pan-tilt mounts, and automated DIY electronics projects. Built with precision injection-molded plastic/nylon internal gears, it provides smooth motion and reliable positioning while adding minimal mass to physical structures.
Operating across a standard voltage range of 4.8V to 6.0V DC, it delivers up to 1.8 kg-cm of holding torque at 4.8V. Its internal analog control circuit provides closed-loop positional control across a full 180° angular movement range (90° in each direction from neutral) via standard 50Hz pulse-width modulation (PWM) signals (1ms to 2ms pulse duration).
Weighing just 9 grams, the SG90 features a standard 3-pin connector wire (Brown = GND, Red = V_CC, Orange = PWM Signal) that interfaces directly with 5V and 3.3V microcontrollers like Arduino, ESP32, ESP8266, and Raspberry Pi. It comes bundled with a selection of plastic servo horn arms and mounting screws for easy mechanical attachment.
