USB data cable tester

Overview

The first low-invasive PCB in 2022, used to test whether various USB cables are broken.
All right. To put it bluntly, it is a network cable tester. It's just used to test the USB cable.
VBUS, CC1, CC2, D-, D+, TX-.TX+, RX-, RX+, GND are independent scanning measurements.
DIAN (ID), SBU1, and SBU2 are rarely used, and the direct power supply shows continuity.
The shell uses the GND signal to show whether the shielding layers of the two ends are connected.
*Because the emark line has MOS, the power supply will be blocked. But it does not affect the judgment of the data pins*

The four TPCs in the upper row are all powered, and are only used to test whether the package is suitable. Just solder any one you want to get electricity.
