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.
Qwiic is cross-platform and is found on SparkFun accessories for the Arduino, BBC micro:bit, and Raspberry Pi along with many of SparkFun’s microcontrollers. It is also directly compatible with Adafruit’s STEMMA QT system.
