Set Up a USB-to-UART Module ()

The does not have a USB-to-UART converter, therefore, you need to use a separate USB-to-UART converter module. A number of modules are available from various vendors; any USB-to-UART module should work.

Finding the COM Port (Windows)

  1. Type Device Manager in the Windows search box.
  2. Expand Ports (COM & LPT) to find out which COM port Windows assigned to the UART module; it is listed as USB Serial Port (COMn) where n is the assigned port number. Note the COM number.

Finding the COM Port (Linux)

In a terminal, type the command:
dmesg | grep ttyUSB
The terminal displays a series of messages about the attached devices.
usb <number>: <adapter> now attached to ttyUSB<number>
There are many USB-to-UART converter modules on the market. Some use an FTDI chip which displays a message similar to:
usb 3-3: FTDI USB Serial Device converter now attached to ttyUSB0
