MODEM contact output signal, data terminal ready, active low MODEM contact input signal, carrier detection, active low MODEM contact input signal, ringing indication, active low ①: The onboard 5V/3.3V can be selected by the jumper cap, or the jumper cap can be unplugged, and the external voltage input can also be used (2.5V/1.8V, except industrial grade).ĥV or 3.3V output for external device (configured by jumper) Mac OS, Linux, Windows 11 / 10 / 8.1 / 8 / 7, Android protection: resettable Fuse, ESD protection.connector: mini-USB, micro-USB, USB Type-A, USB Type-C.Adopts double-sided black immersion gold process, which is durable and has a good look.Support 3.3V/5V output (the module is powered by USB, and the onboard jumper should be shorted to 3.3V or 5V accordingly).Onboard 3.3V and 5V TTL level switch pins for selecting TTL communication level.Onboard IO protection circuits, anti-surge, anti-static, stable, and safe communication performance.Onboard resettable Fuse and Transient Voltage Suppressor, anti-overcurrent and anti-overvoltage, anti-surge, anti-static, improve shock resistance, stable and safe communication performance.Compared with CH340G, it supports a higher data rate (up to 6Mbps) and more serial port IO levels (5V / 3.3V / 2.5V / 1.8V). unwrap this layer and make sure that it stays away from the exposed wires you need to work on (use tape if you need to).USB To UART Module, Micro / Mini / Type-A / Type-C Connectors, High Baud Rate Transmission now there should be another layer of foil like material wrapped around the wires that you need to get to. now pull the braided layer of shielding back and down the cable foe each cable. now take your razor blad and cut down the center of both usb cables making sure not to cut the outer layer of braided shielding on each of them.
leave several inches on the end that you cut off so that you can reuse the end if needed for another project. Next grab a pair of wire cutters ( I used my mini tool to do this) and cut an end of both of your usb cables off.
