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. The adapter’s wires have been color coded:
- Black = GND
- Red = 3.3V
- Blue = SDA
- Yellow = SCL
