This is a 50mm long 4-conductor cable with 1mm JST termination. It’s designed to connect Qwiic enabled components together but can be used for other applications as well.
Each Qwiic Cable’s wires have been color coded to red, black, blue and yellow.
The SparkFun Qwiic connect system is an ecosystem of I2C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can’t hook it up wrong.
