Found on Tindie… The EasyC by e-radionica.com/e-r.io STEMMA/STEMMA QT/QWIIC/GROVE/GRAVITY (compatible) connectors which is the JST connector a lot of us are using. Great to see more adoption of this connector, it’s low-cost, easy to use, and easily available!

Adafruit STEMMA & STEMMA QT Plug & play connectivity

WHAT IS STEMMA? STEMMA is not an original idea, we’re working within an ecosystem of many other plug and play systems. We started STEMMA in 2014, and intended to be compatible with Grove only (cause that’s all that existed at the time) but then when Qwiic came around in 2017, added a smaller connector so we could work with those parts too!

STEMMA attempts to be as cross-compatible as possible with both Grove and Gravity (compatible connectors & 3-5V power/logic). STEMMA QT is cross-compatible with Qwiic - STEMMA QT connector/cable is same as Qwiic. You can use STEMMA QT devices with Qwiic devices/controllers.
