USB3.0 test board

Update: USB3.0-B and USB3.0-MicroB test boards have been produced, and both have passed the verification. Although these three boards are all USB3.0, they can also be used to test USB2.0 lines and connectors.
Original text: The USB test board has a USB3.0-A connector male and female respectively. The two are connected according to the normal USB3.0 line sequence and are led out through a U-shaped pin header, which is convenient for attaching multimeter test leads, oscilloscope probes, and test hooks. wait.
The circuits on the board have been differentially processed and include vias. The actual measurement shows that USB3.0 high-speed signals can be transmitted normally.
The VBUS lines on the male side and the female side are not directly connected, but are connected to two rows of pins and then connected through jumper caps. If you need to measure current, unplug the jumper cap and connect the ammeter.
The male connector adopts universal USB3.0-A, which is easy to purchase. I use the C68740 sold on Lichuang Mall. The pins on both sides of the housing are curved, which can be more firmly fixed on the PCB.
The female connector uses a deep plate-type USB3.0-A female connector (in order to keep it at the same height as the male connector). You can find it by searching for "laptop USB female connector" on Taobao.
