These 30cm long cables will connect any Netduino Go module to your main board.
These cables will work when you need a module to be mounted far from the main board. Not what you'll want to use in most situations, but definitely handy to have in your toolbox.
A note of warning: 30cm is a length where considerations about interference should be taken into account. While simple modules such as buttons and LEDs will work just fine, a module that transmits a lot of information at high frequencies, such as the Display Module, may have problems with this length of cable. It may help reduce interference to have other modules connected to the main board.
