Qwiic

Boards with the 4-pin JST-SH Qwiic I2C connector, which is also compatible with Adafruit’s STEMMA QT. Chain sensors, displays and controllers together with a single cable and no soldering.
The range includes Protocentral’s own Qwiic boards, such as the easyISO isolated Qwiic adapter for galvanically isolating an I2C chain, the tinyGSR and the AS6221 body-temperature sensor, alongside SparkFun and Zio Qwiic modules, HATs and cables.
