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. If you'd like even more details on getting started with the USB host shield, see this great tutorial.Arduino USB Host Shield is a board which gives USB interface features to Arduino board and possibility to stack USB devices to Arduino.

It's pretty impressive that I could just plug a shield into a piece of hardware almost a decade old, load some code on it and it just works.

I then loaded up a HID keyboard sketch, and it worked flawlessly! I was able to type letters on the keyboard connected to the shield and see them appear in the serial monitor. As part of the self-test it connects to the device and displays the USB descriptor in the serial monitor. You also need to have a USB device (like a keyboard) connected during the self-test. Note that to skip the GPIO test, you have to enter any character into the serial monitor and press Send. Also, note that there is a little power switch on the shield that you have to turn on )

On the shield, I first had to connect the D7 pin to the RESET pin. The Arduino sketch uploaded without any problems. I installed the USB Host Shield Arduino library and loaded up the board_qc self-test sketch. This morning I wanted to see if it works, so I plugged it into my old Arduino Duemilanove, released in 2009 and still going. I managed to find the headers last week, and soldered them on at the hackspace last night. The shield doesn't come without any headers, which prompted me to start organising the electronic components I have at the Swansea Hackspace, as I knew I had a spare set of headers there. I then ordered a Sparkfun USB Host Shield from one of the UK distributors, CPC Farnell. A week ago I wrote about building a USB host to Bluetooth LE bridge.
