This is revision 2.0 of USB Host Shield. Thanks to new interface layout it is now compatible with more Arduinos - not only UNO and Duemilanove, but also big Mega and Mega 2560 work with Standard variant of this shield out of the box. No more SPI re-wiring and code modifications, plug and play! This is great shield if you want to interface with Android phone or tablets too :)

This shield is shipped as picture shown, containing populated and tested board plus a set of stackable headers, which is properly soldered.

This shield will work with standard (dual 5/3.3V) and 3.3V-only (for example, Arduino Pro) boards. Arduino clones with standard connector layout, including ICSP connector, should work. The following device classes are currently supported by the shield:

• HID devices, such as keyboards, mice, joysticks, etc.
• USB to serial converters - FTDI, PL-2303, ACM, as well as certain cell phones and GPS receivers
• ADK-capable Android phones and tablets
• Digital cameras - Canon EOS, Powershot, Nikon DSLRs and P&S, as well as generic PTP
• Support for more devices is currently in development.
