Adafruit Stemma is a collection of solderless digital/analog/power/I2C connection standards based on JST PH 2mm 3/4 pin (Stemma) and JST SH 1mm 4 pin (Stemma QT) connectors.
Stemma equipped boards may be compatible with Seed Studio Grove connectors, SparkFun Qwiic connectors or DFRobot Gravity connectors. Cross-compatibility should be checked before interconnecting Stemma/Stemma QT boards with other manufacturer boards, as there could be connector incompatibilities or voltage issues (with Qwiic boards).

Stemma and Stemma QT have compatibility with similar connections used by manufacturers other than Adafruit. STEMMA attempts to be as cross-compatible as possible with both Grove, easyC 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.
See the chart on the Adafruit Stemma/StemmaQT Guide for the latest compatibility charts between Stemma, Stemma QT, Grove, Qwiic, and Gravity connections.
With the volume of hardware using these standards, two separate lists have been creaued:
- Awesome Stemma QT - list of hardware using the 4-pin I2C interface (Stemma QT / Qwiic)
- Awesome Stemma - list of hardware using the three & four pin digital/analog connection.
You can find the up to date list of Adafruit Stemma hardware on Adafruit.
