## Description

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.*
