Thread: 3-axis servo color wiring guide

Tweet

Many have writing asking how to wire their servos.. there is no standard and when I started working on mine, I didnt really see anything in the thread so I thot it out and came up with what seemed logical.. (a pirate using logic?? Unheard of!)

The wiring I use is just a 5'-10' Cat5 router cable.. (you can use Cat5e, 6pair, 8pair or 10pair wire also), I cut the plug off one end of the Cat5 (leaving the other to plug into controller Cat5 sockets), split the wires and twist/solder them such:

Orange/Wht - B+(RED)
Orange - Nod command
Green/Wht - B+ (RED)
Blue - Tilt command
Blue/Wht - GND (BLK)
Green - Rotate command
Brown - Jaw command
Brown/Wht - GND (BLK)

I twisted the bright-striped wires(org/wht & grn/wht) together to carry the B+ (positive) current load, and twisted the dark-striped wires(blu/wht & brwn/wht) together to carry the Ground current load. Single wires by themselves wont carry the current for four servos, hence the twisted pairs. Each of the solid colors go to individual servo command wires(the yellows).

Orange - Nod servo yellow wire
Green - Rotate servo yellow wire
Blue - Tilt servo yellow wire
Brown - Jaw servo yellow wire

If you want to include LED eyes, you can use the Cat5, just wire the LEDS to the Red and Black wires (DONT forget the limiting resistor!). Using intercom(6, 8, 10pair) wires gives you more options(LEDs, moving eye servos, etc), just remember to double up the positive and negative wires to be able to handle all the current.

If you already have a color code, great! No one's code is wrong.. whiche'er one ya use, jus' Keep ta th' Code, 'Mate!!

I did something similar with my cat5e cables. two wires for v+, two for ground and 1 each for 3 control lines.
