This sensor is designed to seamlessly integrate\r\nwith the Qwiic ecosystem for I2C communication, making it a breeze to add to\r\nyour existing projects and daisy-chain with other Qwiic components. If you\r\nprefer to bypass the Qwiic connector and I2C, you can also access the VCC,\r\nTrigger, Echo, and Ground pins broken out on the board's edge. Please be aware\r\nthat this ultrasonic sensor comes uncalibrated, and you will need to\r\nmanipulate the raw output for your specific application. With its wide range\r\nof applications, the SparkFun Qwiic Ultrasonic Distance Sensor is a versatile\r\ntool for robotics projects, obstacle avoidance systems, and any application\r\nthat requires accurate distance measurement without physical contact. Its\r\nadaptability makes it a valuable addition to your toolkit. The SparkFun Qwiic\r\nConnect System is an ecosystem of I2C sensors, actuators, shields and cables\r\nthat make prototyping faster and less prone to error. All Qwiic-enabled boards\r\nuse a common 1mm pitch, 4-pin JST connector. This reduces the amount of\r\nrequired PCB space, and polarized connections mean you can’t hook it up wrong.\u003c\/p\u003e \r\n\r\n\u003ch3\u003eProduct Features\u003c\/h3\u003e\r\n \u003cul class=\"a\"\u003e\r\n \u003cli\u003eNon-contact distance readings: From 2 cm to 400 cmIncludes: 1x Ultrasonic Distance Sensor -
