Boosting Rx signal voltage from 2.7v to 5v.
An excellent item for anyone wanting to use 5v Servos such as hexTronik or Towerpro, on a high-end or microprocessor controlled receiver(Rx) with a Servo signal output of 2.7v.

Weight: 1.5g

DO NOT use on 5v Rxs with a new 2.7v Servo. This will overload the servo.
