SparkFun (PID 09947 USB Host Shield
Product Description
SparkFun (PID 09947 USB Host Shield
- MAX3421E USB Peripheral/Host Controller with SPI Interface
- Arduino shield format
- 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.
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.
