30cm Servo Extension Cable (JR Male to Futaba Female)

Description

The 30cm Servo Extension Cable is a simple but essential wiring component for any electromechanical build. Featuring a standard 3-pin male connector on one end and a 3-pin female connector on the other, this cable instantly adds 30 centimeters (approx. 12 inches) of reach to your standard servos, Electronic Speed Controllers (ESCs), and basic digital sensors.

Whether you are routing cables through the chassis of a competitive mobile robot, carefully managing the wiring on an autonomous drone platform, or simply giving your Arduino-based sensors a bit more breathing room on the workbench, these flexible extensions are indispensable. They are fully compatible with common JR, Spektrum, and Futaba style pinouts, ensuring a snug, secure fit that won't vibrate loose during operation.

Frequently Asked Questions (FAQ)

Q: What do the three wire colors represent?
A: While color schemes can vary slightly by batch, the universal standard is: Darkest color (Black or Brown) is Ground (GND), Middle color (Red) is Power (VCC, usually 5V-6V), and the Lightest color (White, Yellow, or Orange) is the PWM Signal line.

Q: Can I daisy-chain these extensions together if I need more than 30cm?
A: Yes, you can plug multiple cables together to get extra length. However, keep in mind that for very long runs (over 1 meter), the control signal can degrade or experience voltage drop, which might cause servo jitter.

Q: Will this fit my 3-pin Arduino sensors?
A: Yes! Because this cable uses standard 2.54mm (0.1") pitch female headers, it will slide perfectly onto the male header pins of most standard hobby sensors and breakout boards.
