They are used primarily to interface with buttons, rotary encoders and such.

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.

Analogue 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 the Detailed explanation The configuration is shown, when both jumpers are closed, is suitable for official Arduinos, such as UNO, Duemilanove, Mega and Mega 2560.

They are used for different power Configurations. Power Select 2 solder jumpers marked “5V” and “3.3V”. Mass storage devices, such as USB sticks, memory card readers, external hard drives (FAT32 The following device classes are currently supported by the shield:  HID devices, such as keyboards, mice, joysticks, etc.  Operates over the extended -40☌ to +85☌ temperature range  Complies with USB Specification Revision 2.0 (Full-Speed 12Mbps Peripheral, Full-/Low-Speed Specifications Work with standard (dual 5/3.3V) and 3.3V-only (for example, Arduino Pro) boards. Solder included stackable connectors (2x3 ICSP connector's female side should be facing down), plug and No more SPI re-wiring and code modifications - just With the Standard variant of this shield out of the box. Thanks to new interface layout it is nowĬompatible with more Arduinos - not only UNO and Duemilanove but also Mega and Mega 2560 work This is based on revision 2.0 of USB Host Shield. On the MAX3421E (datasheet), which is a USB peripheral/host controller containing the digital logic andĪnalog circuitry necessary to implement a full-speed USB peripheral or a full-/low-speed host compliant The USB Host Shield allows you to connect a USB device to your Arduino board.
