Standard & High-Torque Servo Motor Series
This series of servo motors covers the full spectrum of DIY motion control, from lightweight hobby projects to high-torque robotics. Whether you need the precision of the micro SG90 for a small camera gimbal or the raw power of the metal-geared MG996R for a robotic arm, these servos provide reliable 180-degree rotation (typically) and are compatible with standard PWM signals from Arduino, ESP32, and RC receivers.

Pro-Tip for High-Torque Models
When using the MG995 or MG996R, we strongly recommend using an external 5V-6V power supply rather than powering directly from an Arduino's 5V pin. These motors can draw over 1A under load, which may cause your microcontroller to reset or sustain damage.
