USB Cable Tester Board Data Wire Checker with Acrylic Case LED Indicator for Charging TYPE-C Micro Type A Type B Data Cable Test About Description: Feature: 1. The USB cable tester is a reliable tool used to test the connection status and functionality of USB cables. 2. It features a simple and intuitive design. Users only need to plug the two ends of the USB cable to be tested into the corresponding connectors, and the LED indicators will display the functionality and connection status of the USB cable. This allows users to intuitively understand the cable's status, whether there are missing data transmission lines, high-speed transmission data TX/RX lines, or physical damage leading to disconnection. (Note: The cable's carrying capacity cannot be tested.) 3. PCB Size: 3.35 inches x 2.76 inches (85mm x 70mm) 4. Power: Power 1 - CR2032 button battery, Power 2 - Vin (external power supply)Vin range: 3-12v 5. Measurement types: TypeB 3.0, TypeB 2.0, TypeC 3.0/3.1/3.2, MicroB 3.0, MicroB 2.0, MiniB 2.0, and Lightning. Test 1 When GND and VBUS lights are on, it indicates that the USB data cable only has charging functionality. Test 2 When GND, VBUS, D+, and D- lights are on, it indicates that the USB data cable has both charging and data transmission capabilities. Test 3 When GND, TX2+, TX2-, VUBS, CC2, D+, and D- lights are on, it indicates that the USB data cable has both charging and high-speed data transmission capabilities. It is a USB 3.0, 3.1 or 3.2 cable. Test 4 When all the lights are on (except for one D+ and one D-), it indicates that the USB data cable supports comprehensive functionality, including charging, data transmission, audio, and video transmission. Test Damaged Cable The USB cable tester can detect whether there is a broken wire inside the cable. If a wire is disconnected, the corresponding LED will not light up. For example, if the D+ and D- data lines of the USB Type-C cable are cut, the D+ and D- LED indicators on the USB tester will not illuminate, as shown in the diagram. Because there are various types of USB cables, we are only showing a partial representation in the image, but the method for identifying USB data cables remains the same.
