STEMMA QT / Qwiic Cable Range
The STEMMA QT & Qwiic connect system is an ecosystem of I2C sensors, actuators, shields, and cables that make prototyping faster and less prone to error. Maybe this is why it’s constantly growing in popularity with makers.
All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This is to reduce the amount of required PCB space. Also because polarized connections mean you can’t hook it up wrong.
Because the Qwiic and STEMMA QT ranges are vast, Proto-Pic carries the full range of Qwiic cables to help you connect up your accessories. This includes an adaptor cable to connect Qwiic to the Grove kit from Seeed!

The 28AWG wires have been colour-coded to red, black, blue, and yellow. Additionally, the female Qwiic connector features a basic 1mm pitch. All Qwiic cables have the following color scheme and arrangement:
Cable Pin Out:
- Black = GND
- Red = 3.3V
- Blue = SDA
- Yellow = SCL
