Modified from standard servos, this continuous-rotation 360-degree SG90 micro servo functions as a speed-controllable gear motor with integrated driver circuitry. Instead of moving to a specific fixed angle, adjusting the PWM signal controls the direction and rotational velocity (clockwise, counter-clockwise, or stop). Its lightweight form factor and built-in driver eliminate the need for an external H-bridge, making it ideal for micro-wheeled robotics, small conveyor systems, automated curtain pullers, and rolling platforms.
