Note: This servo cable has been replaced by a new version that has male and female ends that are compatible with both Futaba and JR connectors. The new cable can be used as a drop-in replacement for this cable.

This servo extension cable has three 22-AWG wires joining a male JR connector and a female JR connector, which means it is compatible with almost all of the RC servos Pololu sells (you can assume Pololu servos have female JR connectors unless the servo’s product page specifically says otherwise). The connectors have gold-flashed contacts on a 0.1" spacing.

Note: The cable’s female connector is the same as what is found on most generic servos and fits nicely with 0.1" male headers, but is often referred to as “male” in the RC hobby industry. Likewise, the cable’s male connector is often referred to as “female” in the hobby industry because of the outer shroud, even though it internally consists of three male pins. The pictures below show the cable connectors labeled with Pololu gender convention.

The shrouded male connector on these cables is not compatible with Futaba-style connectors. You can get a Futaba female connector to fit by shaving down its polarizing tab. Alternatively, Pololu has slightly different flat and twisted versions of these cables that have the same female JR connector paired with a male Futaba J connector, which means each end is compatible with both JR and Futaba connectors.

We also sell flat and twisted female-to-female servo extension cables.

Servo cable color convention

  • brown or black = ground (GND, battery negative terminal)
  • red = servo power (Vservo, battery positive terminal)
  • orange, yellow, white, or blue = servo control signal line
