The GM-TTL5P USB to TTL 3.3V/5V Auto Sensing Adapter is a USB to Serial UART (TTL Auto level) adapter. It allows you to connect your computer through an available USB port and uses it as a regular serial communication. All USB protocol is handled within this adapter. There is no other device or programming required and supports plug-and-play technology.

The adapter is perfect for embedded systems that require a serial connection to a computer and is compliant with USB spec. 2.0 &1.1. The board attaches directly to the USB bus via a standard type “A” receptacle connector for upstream data. The USB to Serial UART shows up on any Windows computer as a standard serial COM port. Any applications that talk to this COM port are automatically converted to USB and back to UART to your target board.
