Details

This SS-201BTTL USB to Serial UART is a transistor-transistor logic (TTL level) adapter. It allows you to connect your computer through USB port and use it as a regular serial communication. UARTs transmit one bit at a time at a specified data rate, all USB protocol is handled within this adapter.

There is no other device or programming required. The adapter is for embedded systems that require a serial connection to a computer where a native COM port is not available. The board attaches directly to the USB bus via a standard type A receptacle connector. It shows up on any Windows computer as a standard serial COM port. Any applications that talk to this COM port is automatically convert to USB and back to UART to your target board.
