Overview

The GM-TTL5VT USB to TTL 5V Header Cable is a USB to Serial UART (TTL Level) 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” Male 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.

Additional Features:

• The Cable provides a USB to TTL Serial interface to 6-pin header.
• Single board USB to asynchronous serial data transfer interface
• Entire USB protocol handled by the electronics in the cable USB
• UART interface support for 7 or 8 data bits, 1 or 2 stop bits and odd / even / mark / space / no parity
• Fully assisted hardware (RTS#/CTS#) or X-On / X-Off software handshaking.
• Data transfer rates from 300 baud to 3 Mbaud at TTL levels.
• +5V output allows external logic to be powered from the USB port
• VCC Output rating current Max. 450mA
• Transmit and receive LEDs
• UHCI / OHCI / EHCI host controller compatible
• Low USB bandwidth consumption.
