4 2011-07-08 SparkFun <p> <strong>Description:&nbsp; </strong>This new version corrects the pin out for the GPX and RESET pins. The USB Host Shield contains all of the digital logic and analog circuitry necessary to implement a full-speed USB peripheral/host controller with your Arduino. This means you could use your Arduino to interface with and control any USB slave device - thumbdrives, digital cameras, bluetooth dongles, and much more!</p> <p> A four-wire serial interface is used to communicate with the host controller chip, so the shield connects the Arduino&#39;s hardware SPI pins (D10-13) to the MAX3421E. A USB type A female connector is wired up to the IC, and it also supplies 5V as any normal USB port would.</p> <p> The Host Shield takes its power from the &#39;Vin&#39; pin on your Arduino. Power from that pin is regulated to both 5V and 3.3V on the shield. All SPI signals are sent through a hex converter to step them down to 3.3V.</p> <p> <strong>Documents:</strong></p> <ul> <li> <a href="http://www.sparkfun.com/datasheets/DevTools/Arduino/USBHostShield-v13.pdf" target="_blank">Schematic</a></li> <li> <a href="http://www.sparkfun.com/datasheets/DevTools/Arduino/USBHostShield-v13.zip">Eagle Files</a></li> <li> <a href="http://www.sparkfun.com/datasheets/DevTools/Arduino/MAX3421E.pdf" target="_blank">Datasheet</a> (MAX3421E)</li> <li> <a href="http://www.circuitsathome.com/arduino_usb_host_shield_projects" target="_blank">Projects and Code</a> (Thanks Oleg!)</li> </ul> <p> <strong>Replaces:</strong> <a href="http://www.sparkfun.com/commerce/product_info.php?products_id=9628" target="_blank">DEV-09628</a></p> Arduino USB Host Shield http://www.sparkfun.com/products/9947 USB Host USB Shield GPI0
