DESCRIPTION:

• The TowerPro MG90S is a premium-grade 9g micro servo with full metal gears, offering significantly higher strength and durability than standard plastic gear servos. It provides smooth and reliable 180-degree motion, making it ideal for robotics, RC planes, gimbals, and automation mechanisms requiring greater torque and robustness.
• The metal geartrain ensures long operational life, reduced wear, and better load handling. With fast response, strong torque, and compact size, the MG90S is widely used in precision control applications and DIY robotic platforms. Its standard PWM interface makes it compatible with Arduino, ESP32, Raspberry Pi, and all RC receivers.
