The first is Lime Pulse’s USB cable checker. In addition to the USB-C terminal, USB Micro B and Mini B can be connected, and their connections are displayed with LEDs. This is a measurement of a proper USB-C cable. It can be seen that not only all the wiring of USB 3.1 is connected, but also the GND-VCONN in the C plug has a resistance of 1 kilohm, and the E marker IC is built-in.
The tool shows voltage and current, and the direction of electricity flow (left photo).
The photo on the right is ST Microelectronics power evaluation board STEVAL-ISC0051V1. You can know the status of USB-PD (Power Delivery).
