INT and SS signals can be re-assigned to other pins (see below) SPI signals cannot. However, standard-sized Arduino boards, such as Duemilanove and UNO have SPI signals routed to pins 11-13 in addition to ICSP connector, therefore shields using pins 11-13 combined with standard-sized Arduinos will interfere with SPI. In this group, the shield in its default configuration uses pins 9 and 10 for INT and SS interface signals. Digital I/O pins 0-7, like already mentioned analog pins are not used by the shield and provided only for convenience.

They can be used for many purposes I use it to drive HD44780-compatible character LCD, as can be seen in digital camera controller circuit, as well as this keyboard example. Max_LCD library which is part of standard USB Host library software package uses some of GPOUT pins.

An example of GPIN use can be seen in digital camera controller GPIN pins can also be programmed as a source of MAX3421E interrupt. They are used primarily to interface with buttons, rotary encoders and such. GPIN pins. Eight 3.3V general-purpose digital input pins of MAX3421E.They are provided to simplify mounting and provide pass-through for shields mounted atop of USB Host Shield in a stack. Analog pins are not used by the shield.RESET, 3.3V, 5V and GROUND signals from this connector are used. Power pins are used to connect to power pins of Arduino board.See Power Options section for detailed explanation. They are used for different power The configuration shown, when both jumpers are closed, is suitable for official Arduinos, such as UNO, Duemilanove, Mega and Mega 2560. Power Select 2 solder jumpers marked “5V” and “3.3V”.To achieve the FOR Arduino USB HOST function, you can communicate with other USB devices, and support USB HUB function Storing Devices – USB Memory, SD card reader, harddiskĬompatible with for Arduino following hardware.Digital Cameras – Canon EOS, Powershot, Nikon DSLR and P&S.USB-Serial Converters – FTDI, PL-2303, GPS….HID Devices – Klavye, mouse, joystick.Complies with USB Specification Revision 2.0 (Full-Speed 12Mbps Peripheral, Full-/Low-Speed 12Mbps/1.5Mbps Host).Operates over the extended -40☌ to +85☌ temperature range.Works with standard (dual 5/3.3V) and 3.3V-only (for example, Arduino Pro) boards.It is compatible with Arduino Uno and Mega and with 5V/3.3V selection feature, it can be used with 3.3V boards

MAX3421 is used on board as USB host/SPI converter IC.

Keyboard or mouse can be connected to Arduino with the shield, wireless communication can be done with Bluetooth dongle, you can connect to a barcode reader and even your phone. Arduino USB Host Shield is a board which gives USB interface features to Arduino board and possibility to stack USB devices to Arduino.
