@/servo-enable
Standard servo node with Enable pin added. Detach servo when En is false and allow to free-wheel (or allow other node to control the servo).
PORTnumber
Board port number the servo is connected to.
VALnumber
Desired servo angle or value in unit range [0.0, 1.0]. For standard servo 0.0 would be mapped to 0° and 1.0 would be 180°.
Enboolean
Enable servo. Detach servo if this is false.
