According to the text information in the picture, the following is the extracted content: **Model: PH743 **Color: Black **Transmission speed: USB3.x (depending on the host transmission speed) **Product interface: USB 19P, USB3.2 Type-E** **Product function: Convert the motherboard Type-E or expansion card Type-E interface to the USB 19P interface. **Product advantages:** - Vertical transfer, compact size, no interference with other positions. - Multi-layer circuit board, integrated differential signal optimization technology, stable signal, strong anti-interference ability. When using 19Pin to Type-C data cable, the front of the Type-C interface can support USB3 and USB2, and the reverse is only USB2. When using 19Pin to 2 Type-A□ data cables-one A□ has only USB3 function, and the other A port has only USB2 function (two interfaces can be used effectively, reasonably without wasting resources). When using 19Pin to a single Type-A□ data cable, it may only have USB2 function (no USB3) or only have USB3 function (no USB2). Because each cable has different definitions, the final USB function is different; (The interface can be used effectively and resources are not wasted reasonably)
