The FEETECH FS90R is a compact 9g continuous-rotation micro servo designed for small robotics, Arduino projects, and DIY electronics. Unlike a standard positional servo, it rotates continuously in either direction, with speed and direction controlled by a PWM signal. This makes it ideal for small mobile robots, miniature drive systems, and lightweight automation projects.
Operating from 4.8V to 6V DC, the FS90R features plastic gears, a lightweight design, and a simple three-wire connection for easy integration with compatible microcontrollers.
