Qwiic Cable - Breadboard Jumper (4-pin)

This is a jumper adapter cable that comes pre-terminated with a female Qwiic JST connector on one end and a breadboard hookup pigtail on the other. This cable makes it easy to connect components with a Qwiic connector to a breadboard or an Arduino-based device’s pins.

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 male hookup pins can easily insert into a standard 0.1" connector.


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.

Customer Comments

  • Nice! But I’d like to find both the connectors at the breadboard end, and the tools used to affix them.

  • I’m assuming red and black are vcc and ground. What are the other two colors (blue is SDA and yellow SLC or opposite)?

  • Having an option for the female connectors at the breadboard end would be nice.

    Thanks, Joe
