Whenever you want to connect a device that comes with a serial port to your computer’s USB port, you will need a USB to serial adapter. The logic level can be switched between 3.3V and 5V. This adapter can be used as a USB to RS323 adapter as long the connected device accepts the lower TTL logic level.

We recommend downloading the required USB driver for your operating system from WCH official website.

If you prefer a cable instead of the dongle-style, see our PL2303TA USB-TTL UART interface cable.

    There’s no DTR line.
    So, when uploading for example to an Arduino Pro Mini, you have to push and release the Reset button on the Arduino to get the communication.
    Several trys may be necessary.

    The missing DTR line is right, as to see in the pictures. These very basic adapters only populate the most common signals. If you need different signals, just take a different adapter. We carry FT232, for example.
