شیلد و ماژول USB Host با قابلیت پشتیبانی از Android ADK

معرفی

ماژول USB Host یک ماژول کاربردی بوده و باعث می شود وسایل USB خود مثل کیبورد، موس، حافظه فلش، کارت ریدر و ... را به راحتی به آردوینو خود متصل کنید. این ماژول بر پایه تراشه MAX3421E طراحی و ساخته شده است.این تراشه برای کنترل USB یا تجهیزات مجهز به USB اشتفاده می شود.

ماژول USB Host قابلیت نصب بر روی انواع بردهای آردوینو مانند مگا 2560، مگا 1280، Diecimila / Duemilanove 328 را دارد و از Android ADK پشتیبانی می کند.

با استفاده از این ماژول می توانید دستگاه های USB زیر را به برد آردوینو متصل کنید:

• رابط های کاربری مثل کیبورد ماوس جوی استیک...
• کنسول های بازی مثل PS3 و XBOX
• دوربین های عکاسی مثل  Canon EOS, Nikon DSLRs and P&Sl
• فلش دیسک ها و کارت های حافظه
• و ...

• ولتاژ کاری: 5V
• تغذیه از برد آردوینو یا کانکتور USB
• جریان مصرفی: 400 تا 500 میلی آمپر
• تراشه کنترل کننده: MAX3421E
• پشتیبانی از Android ADK

Introduction

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.
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.
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 orcase. 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. can be audio docking stations, exercise machines, personal medical testing devices, weather stations, or any other external hardware device that adds to the functionality of Android.Accessories use the Android Open Accessory (AOA) protocol to communicate with Android devices, over a USB cable or through a Bluetooth connection. If you are building an accessory that uses USB, make sure you understand how to implement the AOA protocol to establish communication between your accessory hardware and Android. For more information, see the 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.

Specification

Operating Voltage: 5 V From Arduino
USB Controler: MAX3421E
Max Current: 500mA when Arduino is powered by a suitable power supply connected to the Arduino power jack
400mA when Arduino is powered by its USB port
The Arduino USB Host Shield has no power jack and is powered only when attached to an Arduino board
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.
