The Arduino USB Host Shield allows you to connect a USB device to your Arduino board. The Arduino USB Host Shield uses the MAX3421E a USB peripheral/host controller. It contains 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 also has ports that are compatible with TinkerKit modules.
Compatible Device Classes The following device classes are supported by the shield:
For information on using the shield with the Android OS, see Google's ADK documentation.
- 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.
- Bluetooth dongles.
USB Host Shield Features
- USB Controller: MAX3421E
- Operating Voltage: 5V (obtained from your Arduino; the shield has no external power connector)
- Max. Current (Arduino powered via jack): 500mA
- Max. Current (Arduino powered via USB): 400mA
- Dimensions: 2.7 × 2.1 inches
The Arduino USB Host Shield can be used with the USB Host Library for Arduino which can be downloaded below. Your Arduino communicates with the MAX3421E using the SPI bus (through the ICSP header). This is 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.
Input/Output This shield has a male USB port where you can attach your USB device. It also features communication interfaces for adding any TinkerKit modules you may have. This can simplify the creation of a project or a prototype. The on-board TinkerKit connectors are:
- 2 TinkerKit Inputs: IN2 and IN3 (3-pin white), routed to Arduino A2 and A3 analog input pins.
- 2 TinkerKit Outputs: OUT5 and OUT6 (orange), routed to Arduino PWM outputs on pins 5 and 6.
- 2 TinkerKit TWI (4-pin white), routed to the Arduino TWI interface. Both connect to the same TWI to allow you to create a chain of devices.
