MG90S Micro Servo Motor, 180° Position Control Plastic Gear, Analog RC Servomotor, 4.8V–6V PWM for Arduino ESP32 RC Models Robotics, Includes Servo Horns + Mounting Screws
The MG90S Micro Servo Motor (180° Position Control) is a compact and dependable analog RC servomotor built for projects that require accurate angle positioning rather than continuous spinning. It’s ideal for robot arms, steering systems, pan/tilt brackets, RC models, animatronics, and DIY mechanisms where repeatable motion matters.
- 1× MG90S micro servo motor
- Multiple servo horns/arms
- Mounting screws
The MG90S Micro Servo Motor (180° Position Control) is a compact and dependable analog RC servomotor built for projects that require accurate angle positioning rather than continuous spinning. It’s ideal for robot arms, steering systems, pan/tilt brackets, RC models, animatronics, and DIY mechanisms where repeatable motion matters.
This 180° version rotates to a commanded angle and holds position using internal feedback control. With standard RC PWM servo signals, you can easily control it using Arduino/ESP32 servo libraries and most RC receivers.
How 180° Position Control Works (PWM)
A positional servo interprets PWM pulses as a target angle:
- Typical frequency: ~50 Hz
- Pulse width range: ~1.0 ms to ~2.0 ms
- Around 1.5 ms is commonly near the center position
Wiring (Standard 3-Wire Servo Cable)
Typical color mapping:
- Brown / Black: GND
- Red: VCC (4.8V–6.0V)
- Orange / Yellow: PWM Signal
Power Notes (Recommended)
Servos can draw higher current during movement and under load. For best performance:
- Use a separate regulated 5V supply when possible
- Always share ground between the servo and controller
- Avoid powering heavy loads directly from small onboard regulators

- 180° positional control for accurate angle movement
- Micro size for compact robotics and RC builds
