All about the wiring of electronics for your robot. This page is divided into signal wires & power wires.
Here's a preview of the wiring for the Pi and TI configurations. Proceed to the subsections for details.

Signal wires perform the communication on your robot, between sensors, CPU, and actuators. Several wires make up a cable, and the cables get plugged in when you build your robot. All signals on SCUTTLE can be made with regular off-the-shelf Dupont-style terminals, all female. Lengths are 10cm and 20cm as shown.
⚠️ Please do not peel the wires apart! Keep them bonded for strong connections.
Colors Selection
We chose the colors to make good use of any pack of wires. When you add sensors and actuators, try to stay consistent.
| Function | Preferred Color |
|---|---|
| Ground | Black, Brown, Green |
| Power, 3.3v | Red, Purple |
| PWM signals | Orange, Yellow |
| CLOCK (i2C | Gray |
| SIGNAL (i2C) | White |
This section covers cables you can DIY.
