Jumper Wires

You will need jumper wires for making quick and easy prototyping connections between sensors, breadboard and the embedded board. Use them to wire up all the circuits.
Jumper wires can be purchased with male terminations on both ends, female terminations on both ends, or one male and one female termination. These termination are designed for use with 0.1" (2.54 mm) male headers and female headers, solderless breadboards, and prototyping PCBs. The wires are available in vary lengths and colors. The 3" (7.5 cm) wires are useful for the connections on the breadboard; the 6" (15 cm) wires are useful for the connections between the embedded board and breadboard; the 12" (30 cm) wires are useful for the connections between the sensor and breadboard/embedded board.
Here, recommend you to prepare all there types of wires in vary length for the embedded labs:
- Female-Female Jumper Wires: 6", 12"
- Male-Female Jumper Wires: 6", 12"
- Male-Male Jumper Wires: 3", 6"

Dose the color of Jumper Wires matter?
No, the colors do not matter. The wire color is just an aid to help you keep track of which connections are connected and do no affect on the operation of the circuit. You can define your own color-coding scheme, but here we recommend you to follow the rules as below lists, so everybody can understand the way the circuit is wired:
- Black Wire: Negative Power Sources (GND)
- Brown Wire: Data signals
- Red Wire: Positive Power Sources (+5V)
- Orange Wire: In dual power source circuit, orange wires are used for +3.3V power sources. Otherwise, it can be used for Data signals
- Yellow Wire: Clock Signals
- Green Wire: Protective earth ground (PG)
- Blue Wire: Data signals
- Purple Wire: Reset Signals
- Gray Wire: In the mixed signals circuit, using gray wires for Analog Ground (AGND); Otherwise, it can be used for Data signals
- White Wire: for Data signals
