SparkFun Qwiic Multiport
Qwiic, or STEMMA QT, is a very efficient way to quickly prototype an idea, but a lot of Qwiic/Stemma QT driver boards only have one port, and devices have two ports but that's only good for chaining. This Multiport board allows boards that have only one Stemma QT/Qwiic port to be added to the I2C bus. Or, use this hub to add as many I2C devices to the bus as you need. Complete with mounting holes so the board can be added to any system.
This board is one of SparkFun's many Qwiic compatible boards! Simply plug and go. No soldering, no figuring out which is SDA or SCL, and no voltage regulation or translation required. Also, could be used as a throwing star for a gerbil ninja.
