Description

The TITAN USB-TTL is a USB-to-TTL level serial converter board, which provides a simple way to link from a USB port to 5V or 3.3V TTL level serial interface devices. USB-TTL is designed with selectable I/O pins that can be configured flexibly to operate at 5V or 3.3V level to meet the different requirements of microcontrollers of embedded systems. This USB-TTL converter board is suitable for most microcontroller interfaces.

In addition to the signals of RxD, TxD, RTS#, CTS#, the USB-TTL can provide +5VDC or +3.3VDC power output from the corresponding 5V or 3.3V TTL level serial interface setting. VCC power from pin-1 on the green terminal block connector can be configured for +5VDC or +3.3VDC output at 350mA. By default, +5VDC is enabled.

The USB-TTL is very easy to use. When it is connected to a computer and embedded system, the USB-TTL converter board looks like a virtual COM Port.
