This cable has a standard USB (such as USB 2.0 or 3.0 male connector) on one end, but a 10-pin terminal block on the other end. This design determines that its purpose is not to connect to "finished devices", but to lead out several signals of the USB interface and connect them to devices or development boards in development, debugging, and testing scenarios.
Moreover, it usually does not have a chip and cannot complete data handshakes and protocol recognition like USB. When plugged into a computer, it will not automatically recognize what device you are connected to, so it does not have the "USB device communication" function. At the same time, although it can lead out power lines such as VCC and GND, the power output capacity is unstable and there is no protection circuit. If it is connected incorrectly, it is easy to burn the board or burn the wire. It is not suitable for use as a formal power supply solution.
