I'm trying to connect this servo to my RPi3 with as little wire as possible. What is this red, black, green wire called that allows me to connect a servo to my Pi? enter image description here

  • they are called jumper wires. From the pictures I can't tell the gender, but these come with male and female ends. – Steve Robillard Jan 18 '17 at 21:34
  • You need some male to female jumper wires. The female end will plug into the Pi's male pins. The male end will plug into the female servo plug. – joan Jan 18 '17 at 21:38
  • @joan If it's male female jumper wires, why do I need any in the first place? can it just plug right into the GPIO? – user5812721 Jan 18 '17 at 22:38
  • No, because you need adjacent expansion header pins which are ground, then 5V, then a GPIO. There are no such pins. – joan Jan 18 '17 at 22:50
  • @joan I'm sorry for my lack of understanding, but to clarify, a jumper cable has the adjacent expansion header pins and 5V in it? So all I would need to connect a RPi3 to this servo is just 3 male female jumper cables? – user5812721 Jan 18 '17 at 22:55

Buying jumper wires premade would do the job. If you really want to make them yourself you need some hookup wire and some dupont/rectangular connectors. There's a crimp tool that goes with them, but generally I just use a dab of solder and some fine pliers to close the crimp. They're finicky though - a millimetre out of place into the metal part with the solder and it won't fit into the plastic housing.

  • Look at where the jumper cables meet the servo cables, do I need to buy that black thing or is that just something to keep the wires together? And do I need the jumper wires at all? Could it just plug straight into the GPIO? – user5812721 Jan 18 '17 at 22:39
  • The 'black thing' is just the connectors on the ends of the wires plugged into each other. Take a look at some dupont connectors. The servo will come with a connector attached to its cable. You'll need to run your own male to female jumper wires from that connector to a GPIO pin, 5V and GND. – goobering Jan 18 '17 at 23:09
