Review on 4-Pack 3.3V 5V FT232RL USB to TTL Serial Converter Adapter Module for Arduino by Troy Early

Very inexpensive serial board. After downloading the Windows drivers from the FTDI website, the serial port showed up as VCP and I was able to connect to my application. Download and run the executable setup file from the FTDI website. It's a bit tricky and tricky, but you can get there quite easily. I connected the RX and TX pins directly to the corresponding TX and RX pins of my application along with a GND connection. Choose the right voltage level for your applications. I used 3.3V.
