USB to 5V TTL Header

This USB to Serial UART (TTL level) adapter. It allows you to connect your computer through USB port and use it as a regular serial communication. All USB protocol is handled within this 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 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.
