This means that if the cable fits then it can be used! Make sure the power adapter has the correct voltage (typically 7-12 volts) when applying this logic however. When figuring out cables for Arduino, I like to use the “where it fits” rule. My Arduino Uno powered from a USB phone charger using a USB Type B cable To power the Arduino over a longer distance a regular AC power cable can be used in conjunction with a suitable power adapter. A power adapter cable can also be plugged into the Arduino to power the board when separate from a USB power source.Īs a general rule, the length of cable used to connect the Arduino should be no longer than 5 meters though it is recommended to keep the cable under 3 meters of length. A USB Type B cable can be used for the most popular Arduino model (Uno), however other Arduino boards may require Type B-mini or micro connectors. This guide aims to make it easier for you to figure out which cables and wires you need to power, program, and use your Arduino.Īn Arduino typically only requires a USB cable to be used as a power source and to connect to a computer for programming.
I had to figure out which cables and wires I needed to program and power my Arduino, connect any shields I wanted to use, and start to build projects.
Cables were not included when I first purchased my Arduino.
