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 colour-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 colour 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.
