These USB-SER-NANO boards are the
USB to Serial RS-232 (5VTTL or 3.3V
level) converter module. They allow you
to connect your computer through USB
port and use them as the regular serial
communication. All USB protocol is
handled within the module. There is no
other device or programming required.
These board features innovations that
set them apart from other USB to Serial
Converter boards. Innovations feature
like 256 byte receive buffer and 128 byte
transmit
smoothing technology to allow for high
data throughput. The voltage levels at
TX and RX pins are 0 and 3.3V for USB-
SER-NANO-3.3 and 0 and 5V for USB-
SER-NANO-5. That mean the TX and
RX pins from the USB-SER-NANO can
be connected directly to RX and TX pins
of your preferred microcontroller or any
serial RS-232 application.
The USB-SER-NANO boards are perfect
for embedded systems that require a
serial connection to a computer. The
boards attach directly to the USB bus via
a standard type mini B 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 RS-232 to your target board.
Drivers are available for Windows 98,
98SE, ME, 2000, Server 2003, XP,
Vista, XP Embedded and CE.NET 4.2 &
5.0. Mac OS8/9, OS-X and Linux 2.4
and greater are supported.
