I've bought some crimpers and a dupont connection kit and I'm planning on reusing some old cat5 ethernet cables I have.
Is it reasonable to connect two devices to the RPi via the 8 wires in the cat5 cable? For example connecting four jumpers to 4 GPIO pins on the RPi connecting to one device and the other four cables in the cat 5 cable to four other jumpers on the RPi connected to a second device?
This is attractive because it keeps the wiring (that will be visible) reasonably tidy but I'm not sure if this approach is technically appropriate.
