Pololu 779 - Servo Extension Cable 6" Female - Female

This servo extension cable has female JR connectors on both ends, so it can be used to make connections between devices with 0.1" 3-pin male headers, such as between RC servo controllers or RC receivers and motor controllers with an RC interface. The cable’s connectors are commonly found on RC servo leads and work with both male JR and male Futaba J connectors. They have gold-flashed contacts on a 0.1" spacing and are joined by 22-AWG, 60-strand wires that make this cable more flexible than standard servo cables.

Note: The cable’s female connectors are 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. The picture below shows the cable connectors labeled with our gender convention.

These female-to-female cables are available in two styles: flat, with wires stuck together side by side, and twisted, with wires twisted around each other to decrease electromagnetic interference (EMI). The twisted versions are especially soft and flexible. These cables are also available in three lengths: 6", 12", and 24".
