The Arduino USB Host Shield allows you to connect an USB device to
your Arduino.
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 isTinkerKit 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.
For information on using the board with the Android OS, see:
‐ 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.

Tutorials
With an Arduino HSB Host Shield you can even control an RC car using an XBOX
wireless game controller. Many tutorials are available online, here you can find

Power
The Arduino USB Host Shield has no power jack and is powered only when attached
to an Arduino board.
Input & Output
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.
Physical Characteristics
The maximum length and width of the Motor Shield PCB are 2.7 and 2.1 inches
respectively. Four screw holes allow the board to be attached to a surface or case.
Note that the distance between digital pins 7 and 8 is 160 mil (0.16"), not an even
multiple of the 100 mil spacing of the other pins.
