StemmaQt / Qwiic
The StemmaQT (from Adafruit) and Qwiic (from SparkFun) standards are a compatible system for easily connecting Devices to a Controller using I2C. They use a common 4 pin JST PH connector
There are a wide variety of StemmaQT and Qwiic devices which can be quite useful for effects. See supported devices for information on devices you can use in your project.
