SC1258TG Standard Size Coreless Digital Servo


The SC1258TG is a high speed standard size servo which combines leading edge technology with super high 12-bit (4096) resolution for smooth operation.

How Far Will This Servo Rotate?

The answer to this question is partially dependant on what you are using to control the servo.

With an Average Radio System:
Your average transmitter and receiver will output a relativly narrow PWM signal range.

Radio System + Servo Stretcher:
Adding a Servo Stretcher to your radio system setup will allow you to achieve wide PWM signal ranges.

Wide Signal Controllers:
Controllers such as the Actobotics® Servo Controller, Arduinos, and Raspberry Pi servo hats can usually send a wide signal.
