Depending on the cable you need to make (microUSB, headphone jack, USB-C or just pins on the board) the process might be different. It's helpful to have a breadboard and some goldpin connector cables to go with it, as it makes putting together and tweaking the cable easier and reduces the amount of soldering that has to be done. You can find the build instructions for your cable on the [[Serial debugging:Cable schematics]] page.
There are several ways to connect wires to a microUSB plug:
