This is a "reversed" i2c jumper cable designed to connect modules that use the less common pin ordering (SCL-SDA-GND) to your i2c ecosystem. It comes in a single length (20cm), has yellow shrink-wrapped ends, a hand-applied artisanal polarity marking, and an assortment of festive rainbow colors for the wires themselves.

Some modules that use this pin ordering are the ER-301 and Matrixarchate.
