Digital Display for HC-SR04 Ultrasonic Distance Measurement Control Board
The HC-SR04 Ultrasonic Distance Measurement Control Module automates the use of the HC-SR04 Ultrasonic Range Finder module and provides a direct readout of the distance. The module has several uses. One is simply to easily test HC-SR04 Ultrasonic modules without having to wire them up to an MCU. Another is to provide a display of the distance data such as when using the HC-SR04 on a robotic vehicle and you want an easy way to monitor the distance that the HC-SR04 thinks it is seeing. There is a 4-pin female header on the assembly for plugging in the HC-SR04 ultrasonic sensor. The sensor is inserted so that it points away from the LED display. Power and ground can be supplied via the 6-pin male header as shown below or by connecting to the 2-pin JST XH style connector on the board. Observe the polarity markings on the board if using the JST connector.>
