【產品簡介】

此款新的USB轉接擴充版，可以直接讓Arduno能夠和USB設備進行連接控制，板子用的是Maxim的MAX3421E晶片，和Arduino用SPI接口通信，讓你輕鬆地從任設備如隨身碟、數位相機、藍芽傳輸器等等進行操控～！

This new version corrects the pin out for the GPX and RESET pins. The SparkFun USB Host Shield contains all of the digital logic and analog circuitry necessary to implement a full-speed USB peripheral/host controller with your Arduino. This means you could use your Arduino to interface with and control any USB slave device - thumbdrives, digital cameras, bluetooth dongles, and much more!

A four-wire serial interface is used to communicate with the host controller chip, so the shield connects the Arduino’s hardware SPI pins (D10-13) to the MAX3421E. A USB type A female connector is wired up to the IC, and it also supplies 5V as any normal USB port would.

The Host Shield takes its power from the ‘Vin’ pin on your Arduino. Power from that pin is regulated to both 5V and 3.3V on the shield. All SPI signals are sent through a hex converter to step them down to 3.3V.
