Custom PWM Cables and R69

I've had good luck with the folks at Hansen Hobbies: http://www.hansenhobbies.com/products/connectors/

Custom-length PWM cables really clean up your robot's wiring. And if you need longer cables, this is the best solution (two PWM cables end-to-end is asking for trouble).

We've used www.HansenHobbies.com ourselves about 3 or 4 times for such. Very reliable and quick to ship, except for one time when it took 3 weeks.

I have a different question regarding the PWM cables. There are three wires,

White-Signal
Black-Ground
red- +5V

In other robotic projects I'm able to wire my ESCs using only the White cable. Which is really the only thing that the RC needs to see. I was wondering if this is legal or not in first (to use only the white wire that is)

Daniel,
The speed controllers do not use the 5 volt wire but do use the signal wire and ground. I am having a brain cloud on the Spikes, but I believe all three wires are in use but the relay outputs are different than the PWM outputs on the RC. The servos use all three. I would prefer to use the standard PWM cable for all three and have standard wiring throughout the robot.

You are correct. You've got ground, forward, and reverse. I honestly couldn't tell you which is forward and reverse, but I know all three are in use.

I don't think that it's a good idea to use 1-wire or 2-wire PWM cables because it's non-standard and I'm not sure if it would cause the parts to malfunction. It's not worth the risk; you don't gain that much weight from leaving the PWM cables alone.

The spikes use all 3 wires. The red and white wire are for the fwd and rev signals. The black is ground.

Unless the device needs +5volts of power, then only the ground and signal wires are needed.
