This is a tiny, lightweight, and incredibly popular analog servo motor used in DIY electronics, robotics, and RC (radio-controlled) models. It is designed to rotate precisely to a specific angle, rather than spinning continuously like a standard DC motor.

Key Features:

· 180° Rotation Range: Can precisely rotate its output shaft from 0 to 180 degrees, with a built-in potentiometer for accurate position feedback.
· Compact & Lightweight: Weighs only 9 grams (as printed on the label), making it ideal for micro-robots and small mechanisms.
· High Torque for Size: Provides approximately 1.6 kg·cm of torque at 4.8V, strong enough to move small arms, wheels, or flaps.
· Standard 3-Wire Control: Uses a simple three-pin connection (typically brown/black = Ground, red = 5V Power, orange/yellow = Signal/PWM). It can be driven by Arduino, Raspberry Pi, or any microcontroller with PWM output.
· Durable Plastic Casing: The blue, translucent housing includes built-in mounting ears with screw holes for easy attachment to frames.
· Included Accessories: Almost always comes with a set of three different white plastic servo horns (arms) and small mounting screws to attach the shaft to your mechanism.
