Use this adapter cable as a simple, reliable way to connect I2C sensors with a JST GH connector to your existing QWIIC / STEMMA QT hardware.
With more and more boards and sensors adopting the QWIIC and STEMMA QT standards, a single cable is often all you need to get devices talking to each other correctly. No soldering, no guessing which wire goes where, and no risk of damaging your board from a miswired connection. Just plug it in, write your code, and you are good to go.
