The Qwiic Module for Tessel 2 connects the I2C bus (GND, 3.3V, SDA, and SCL) on the Tessel 2 to the SparkFun Qwiic system. Just plug the module onto either Tessel Port (A or B), plug in a cable, and start playing with a variety of sensors and actuators. There are two connectors, all on the same I2C bus, so you can connect multiple devices.

The module comes soldered with a male header so you can get started immediately! We also exposed a 2nd row of hardware pins so that you can create connections to the hardware pins (Serial, SPI, and GPIO) if needed.

The Qwiic system enables fast and solderless connection between popular platforms and various sensors and actuators. You can read more about the Qwiic system here. We carry 50mm, 100mm, 200mm, 500mm, and breadboard friendly Qwiic cables.

We do not plan to regularly produce SparkX products so get them while they’re hot!

Experimental Product: SparkX products are rapidly produced to bring you the most cutting edge technology as it becomes available. These products are tested but come with no guarantees. Live technical support is not available for SparkX products. Head on over to our forum for support or to ask a question.
