compliant to USB specification rev 2.0. The
shield is Tinker Kit compatible, which means you can quickly create projects by plugging Tinker Kit modules onto the board.
The following device classes are supported by the The Arduino USB Host Shield allows you to connect a USB device to
your Arduino board. The Arduino USB Host Shield is based on the MAX3421E (datasheet),
which is a USB peripheral/host controller containing the digital logic
and analog circuitry necessary to implement a full-speed USB peripheral
or a full-/low-speed host compliant to USB specification rev 2.0. The
shield is Tinker Kit compatible, which means you can quickly create projects by plugging Tinker Kit modules onto the board.
The following device classes are supported by the shield:
- HID devices: keyboards, mice, joysticks, etc.
- Game controllers: Sony PS3, Nintendo Wii, Xbox360.
- USB to serial converters: FTDI, PL-2303, ACM, as well as certain cell phones and GPS receivers.
- ADK-capable Android phones and tables.
- Digital cameras: Canon EOS, Powers hot, Nikon DSLRs and P&S, as well as generic PTP.
- Mass storage devices: USB sticks, memory card readers, external hard drives, etc.
- Bluetooth dongles.
- Google's ADK documentation.
- Arduino's ADK documentation.
Arduino communicates with the MAX3421E using the SPI bus (through the ICSP header). This is on digital pins 10, 11, 12, and 13 on the Uno and pins 10, 50, 51, and 52 on the Mega. On both boards, pin 10 is used to select the MAX3421E. Pins 7, 8 and 9 are used for GPX, INT and RES pins.
Summary
| Operating Voltage | 5V |
| USB Controller | MAX3421E |
| Max Current | 500mA when Arduino is powered by a suitable power supply connected to the Arduino power jack |
| Max Current | 400mA when Arduino is powered by its USB port |
Arduino Library
The Arduino USB Host Shield can be used with the "USB Host Library for Arduino" hosted by Oleg Mazurov and Alexei Glushchenko from circuits@home, Kristian Lauszus and Andrew Kroll on GitHub
