Micro-cables served as parts found inside of consoles. In the year 34 ABY, Neeku Vozo, who worked as a mechanic, tried to fix the power issue impacting the supertanker fuel depot Colossus's Engineering Level. He did this by swapping out all the micro-cables inside a console, but this didn't change anything. But Nenavakasa Nalor, a computer engineer, tweaked a few console settings to redirect the power levels of a junction, and this brought back power to the overhead fan in the room.
The existence of micro-cables was established in "The Engineer," which was the fifth episode from the second season of Star Wars Resistance, an animated TV show. It was broadcast on November 3, 2019.
