SparkFun Qwiic Connect System

Prototyping with I2C has never been easier.

SparkFun's Qwiic Connect System uses 4-pin JST connectors to quickly interface development boards with sensors, LCDs, relays and more.
No Soldering - Qwiic cables (4-pin JST) easily connect development boards to sensors, shields, accessory boards and more, making easy work of setting up a new prototype.
Polarized Connector - There's no need to worry about accidentally swapping the SDA and SCL wires on your breadboard. The Qwiic connector is polarized so you’ll have it wired correctly every time, right from the start.
Daisy Chain-able - Leverage the power of the I2C bus! Most Qwiic boards have two or more connectors on them, allowing multiple devices to be connected.
With more than 150 Qwiic products, you’re sure to find the right board, sensor or shield for your needs.
