DORHEA 12x MG90S 360° Micro Servo Motors — 9G Servos for Raspberry Pi & DIY RC Projects

Overview

The DORHEA MG90S 360° micro servo kit brings compact, high-precision motion to tight spaces. With 12 identical servos weighing around 9 g each, this bundle is ideal for small robotics, camera pan rigs, and modular RC builds. The 360° rotation opens up new design possibilities beyond standard servos, from smooth pan-tilt arrangements to compact steering or motion systems. The gear train is engineered for quieter operation, helping maintain a calmer sound profile in indoor settings or classrooms while delivering crisp, repeatable responses.

Practical uses

• Perfect for micro RC models such as helicopters, boats, cars, and drones
• Great for DIY robotics projects with Raspberry Pi or Arduino
• Ideal for compact pan/tilt cameras and small-motion automation
• Educational kits to explore servo control, sequencing, and motion design

Setup and tips

The servos are controlled by PWM signals. If the PWM signal halts, the servo stops; resuming from a zero signal begins a new 360° sweep. Start calibration from the 1500 μs center and adjust within the 500–2500 μs range to suit your mechanism. The factory baseline is 90°, so you may need to remap signals in your controller for your desired angles. This kit is not intended for large fixed-wing aircraft; it shines in compact, precision-focused projects and educational experiments.
