Pololu – Pololu USB-to-Serial Adapter
For some programs, it will be necessary to connect the handshaking lines
(RTS,phone tv, CTS, etc.) if the software does not establish a connection without those lines. In general,ball gown wedding dresses, the handshaking lines can be left disconnected, used for their intended purpose,green laser 200mw, or used as additional I/O lines to the computer.

Note: This product does not include printed documentation or software discs. The Pololu USB-to-serial adapter requires software drivers to operate; please see the resources tab for more information. This product requires a USB A to mini-B cable (not included) to connect to a computer.
The Pololu USB-to-serial adapter is great for connecting microcontroller projects to a personal computer. The adapter uses 3.3 V signal levels so you can connect it directly to any microcontroller running at up to 5 V without the hassle of an RS-232-to-TTL level converter. The tiny unit is less than 1.0" x 0.7" including its mini-B connector,m2 card reader, and the simple layout of the ground,quad band dual sim mobile, transmit, and receive lines allows for easy mounting that takes up as little as four breadboard rows.

To connect a serial device to your computer’s USB port, you will most likely only need to use the GND,plus size wrap dress, TX,memory sd card reader, and RX lines. The TX and RX lines use 3.3-volt levels, but the USB adapter input lines will tolerate up to 5.5 volts. Therefore,itouch 2.2.1, a direct connection to a microcontroller’s I/O lines is usually possible.
With the trend toward removing serial ports from new computers, the Pololu USB-to-serial adapter provides one of the most economical,smart card, small, and simple solutions to the common problem of interfacing small projects to PCs.
Device specifications PCB size: 1.0" x 0.65" including connector USB standard: USB 2.0 (full speed) Connector: USB mini-B Data I/O voltage levels: 3.3 V (5 V tolerant) Maximum data rate: 921.6 kbps Supply current: 25 mA
The USB adapter’s drivers make it look like a standard serial port to the operating system,firewire cf card reader, allowing you to connect to all of your existing software, such as servo controller interface programs, through a USB port. The adapter is compatible with USB 2.0
standards and allows baud rates of up to 921.6 kbps. Drivers are available for Windows 98 through Vista,1 watt led flashlight, Linux,small spy cameras, and Mac OSX.
