Four screw holes allow the board to be attached to a surface or case. The maximum length and width of the Motor Shield PCB are 2.7 and 2.1 inches respectively. Both connect to the same TWI interface to allow you to create a chain of TWI devices.
Upon init, only Start is written to the Serial Monitor. The shield features several TinkerKit input/output and communication interfaces. I am powering the Arduino Uno r3 + USB Host Shield via USB. This shield has a Type-A USB receptacle where you can attach your USB device. The Arduino USB Host Shield has no power jack and is powered only when attached to an Arduino board.
Many tutorials are available online, here you can find some tutorials developed by Bluetooth HID devices With an Arduino HSB Host Shield you can even control an RC car using an XBOX wireless game controller. Reset your board (ESP8266) Note: You cant hot-plug your USB device (at least in the examples), you need to reset the board each times. Open Serial Monitor (115200) Plug an USB device. The Arduino USB Host Shield can be used with the "USB Host Library for Arduino" hosted by Oleg Mazurov and Alexei Glushchenko from Kristian Lauszus and Andrew Kroll on GitHub ( download). There is a lot of examples in USB Host Shield Library 2.0In order to test that everything is working correctly, you should first try USBdesc.
Use the Arduino Software (IDE) to start tinkering with coding and electronics. In the Getting Started section you can find all the information you need to configure your board. You can find here your board warranty information. Pins 7, 8 and 9 are used for GPX, INT and RES pins. On both boards, pin 10 is used to select the MAX3421E. This is on digital pins 10, 11, 12, and 13 on the Uno and pins 10, 50, 51, and 52 on the Mega.
No more SPI re-wiring and code modifications! This is a great shield if you want to interface with Android phones or tablets too :)
Thanks to the new interface layout it is now compatible with more Arduinos - not only UNO and Duemilanove but also big Mega and Mega 2560 work with Standard variant of this shield out of the box.
