Data Sheet

Typical wiring diagram for the Pololu RC Switch with Digital Output.

The RC switch can be plugged directly into an RC receiver or servo controller using a Female-Female servo extension

cable. These can be found in our Servo Cables [https://www.pololu.com/category/112/servo-cables] category. The switch will

read the signal from the RC receiver, but in the default configuration it will not draw or supply any power to the

receiver, so the power wire is optional. The receiver will need its own power source.

Power for the switch’s logic needs to be applied to GND and VCC and must be between 2.5 V and 5.5 V. Many

microcontroller boards have a 3.3 V or 5 V line that powers the microcontroller and would also be suitable for

powering the RC switch.

The OUT line can be connected to a digital input pin on the microcontroller.

Power jumper

The setup described above involves two separate power supplies. For some applications, this setup can be simplified

by bridging the VCC=VRC power jumper on the bottom of the board. This allows you to either power the

microcontroller and RC switch from the RC receiver’s power supply or to power the RC receiver and RC switch from

the microcontroller’s power supply.
