Sub-Micro Servo 3.7g (Generic) This generic sub-micro servo is one of the lightest servos we carry, weighing just 3.7 g (0.13 oz) without the lead. It is intended for use between 4.8 and 6 V (i.e. with 4- or 5-cell NiMH or NiCD battery packs). Servo horns and associated hardware are included.
Servo control. Servo control is achieved by sending a servo a PWM (pulse-width modulation) signal, a series of repeating pulses of variable width where either the width of the pulse (most common modern hobby servos) or the duty cycle of a pulse train (less common today) determines the position to be achieved by the servo.
