This USB to Serial UART (TTL level) adapter allows you to connect your computer through USB port and use it as a regular serial communication. All USB protocol is handled within the USB to TTL Header adapter. There is no other device or programming required. The adapter is perfect for embedded systems that require a serial connection to a computer. The board attaches directly to the USB bus via a standard type A receptacle connector. It operates on any Windows computer as a standard serial COM port. Any application that talks to this COM port is automatically converted to USB and back to UART (universal asynchronous receiver/transmitter) to your target board.
