9g 180° Micro Servo for Arduino (1.3kg)

The 9g 180° Micro Servo is a lightweight, cost-effective actuator designed for small robotics and automated mechanisms. Powered between 4.8V and 6V, it delivers up to 1.3kg·cm of torque for compact projects where weight and space are critical. It is well suited to students, educators, and hobbyists building with Arduino, micro:bit, or ESP32 microcontrollers.

Compact 9g form factor

Weighing just 9±1g and measuring 22.9 x 12.2 x 30mm, this mini servo is built for space-constrained assemblies and miniature robotic joints. An integrated 250±5mm lead offers convenient cable routing inside small enclosures and robot chassis.

180-degree positional control

Providing a 180°±5° operating angle with a centering difference of 1° or less, this actuator ensures dependable angle positioning. It is ideal for open-and-close mechanisms, gauge indicators, miniature grippers, and pan-tilt structures.

Standard PWM signal compatibility

The servo uses standard PWM control with a 500µs to 2500µs pulse range and a 1500µs neutral point. This enables seamless code integration using standard servo libraries on Arduino, ESP32, and BBC micro:bit boards.

Reliable light-duty torque ratings

Running on 4.8V to 6V, the motor generates a stall torque of ≥1.0kg·cm at 4.8V and ≥1.3kg·cm at 6V, with no-load speeds up to 130±10 RPM. Standby current remains under 40mA, supporting battery-powered educational models and lightweight mechanisms.

STEM and desktop robotics applications

This micro actuator is well matched to classroom demonstrations, Beam robotics, interactive props, and introductory automation experiments. It offers accessible movement for prototyping without adding unnecessary weight or complexity.
