Description。The SparkFun Qwiic Adapter provides the perfect means to make any old I2C board into a Qwiic-enabled board. This adapter breaks out the I2C pins from the Qwiic connectors to pins that you can easily solder with your favorite I2C-enabled device.。The Qwiic Adapter has two Qwiic connection ports， all on the same I2C bus. Four plated through holes are broken out for SCL， SDA， 3.3V and GND. These pins can be used to convert an old I2C-enabled device into a Qwiic-enabled board.。The SparkFun Qwiic Connect System is an ecosystem of I2C sensors， actuators， shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch， 4-pin JST connector. This reduces the amount of required PCB space， and polarized connections mean you can't hook it up wrong.。Get Started with the SparkFun Qwiic Adapter Guide。Features。2x Qwiic Connection Ports。Broken-out I2C Pins

Description。USB-C is fantastic. What makes this cable even better is that one of the features we love so much about USB-C has been replicated to the USB-A 2.0 plug! These cables have minor， yet genius modifications that allow them to be plugged into their ports regardless of orientation. No longer will you fight the USB "super position" where both orientations of your plug seem incorrect. A simple solution to a problem that nearly everyone has faced.。Until we have converted all our hubs， chargers， and ports over to USB-C this is the cable you're going to need for basic USB 2.0 connections. This cable is much thinner and flexible than its 3.1 counterpart and is perfect for USB to serial applications as well as for direct connection to basic microcontrollers.。This cable has the D+/D- wires along side large-gauge VBUS/GND wires. Rated for 2A， we've successfully pulled 2A@5V with minimal voltage drop. If you're looking for a the full USB-C implementation checkout our USB 3.1 cable.。Features。Reversible USB-A connector。Reversible USB-C connector
