Overview
The Kpower M0090 is a metal-gear micro servo for RC aircraft, UAV mechanisms and micro robots. Its DC brushed motor delivers a listed stall torque of 3 kg·cm at 6 V, while the 14 g weight supports lightweight mechanisms. A translucent blue plastic housing, mounting ears and interchangeable horns provide practical integration features for compact motion-control projects.
Features
- Metal gears driven by a DC brushed motor.
- Potentiometer position sensing and two ball bearings (2BB).
- Translucent blue plastic housing with mounting ears.
- 120° travel angle, with customization stated.
- 25T horn spline with a 4.8 mm diameter.
- Listed control protocols: PWM, TTL and RS-485.
