USB – TTL Serial Communication and Programming Adapter CH340 3.3V / 5V
FREE Canada & USA shipping available (see details)
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.
