Convert any conventional servo into an SBUS compatible servo.
A compact and easy to use SBUS decoder allows you to convert any conventional PWM servo to an SBUS compatible servo. This decoder converts an SBUS output to a PWM signal for use by a conventional servo. FrSky recommends using the Servo Channel Changer, listed in the related items section below, to set the desired channel for your servos.
