Zio Ultrasonic Distance Sensor - HC-SR04 (Qwiic)

You may be familiar with the classic HC-SR04 distance sensor, it is great for providing non-contact distance readings from 2cm to 400cm. This board improves on the classic by adding a Qwiic connector to it, so now you can communicate over I²C. If you prefer to bypass the Qwiic connector and I² you can also access the Trigger and Echo pins which are broken out on the edge of the 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.
