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, 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 TinkerKit compatible, which means you can quickly create
projects by plugging TinkerKit 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, Powershot, Nikon DSLRs and P&S, as
well as generic PTP.
* Mass storage devices: USB sticks, memory card readers, external
hard drives, etc.
* Bluetooth dongles.

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.


Operating Voltage

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


This shield has a MALE USB port where you can attach your USB device.

The shield features several TinkerKit input/output and communication
interfaces. Connecting TinkerKit modules can simplify the creation of
a project or a prototype. The on-board connectors are :

* 2 TinkerKit Inputs: IN2 and IN3 (in white), these connectors are
routed to the Arduino A2 and A3 analog input pins.
* 2 TinkerKit Outputs: OUT5 and OUT6 (in orange), these connectors
are routed to the Arduino PWM outputs on pins 5 and 6.
* 2 TinkerKit TWI: these connectors (4-pin in white) are routed on
the Arduino TWI interface. Both connect to the same TWI interface to
allow you to create a chain of TWI devices.
