This is a jumper adapter cable that comes pre-terminated with a female Qwiic JST connector on one end and female connectors on the other. This cable makes it easy to connect components with a Qwiic connector to the male pins on various development platforms. This cable is also a great way to attach a logic analyzer to your I2C system.
The 28AWG wire's length is 150mm (about 5.9 inches). The adapter’s wires have been color coded to red, black, blue and yellow. Additionally, the female Qwiic connector features a basic 1mm pitch, while the female hookup pins can easily connect to a standard 0.1" male connector.
All Qwiic cables have the following color scheme and arrangement:
Black = GND
Red = 3.3V
Blue = SDA
Yellow = SCL
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.
