Arduino USB Host Shield

Overview

The USB Host Shield contains all of the digital logic and analog circuit necessary to implement a full-speed USB peripheral/host controller with Arduino. This shield adds USB Host capabilities to popular Arduino platform. C Software support for new devices is constantly added; at the moment, code for USB keyboard and PS3 controller are ready with Bluetooth and digital cameras in the works.

Features

• USB 2.0 Full Speed compatible
• 3.3/5V operation level compatible
• All GPIOx pins break-out
• USB Host 5V/500mA supply for USB protocol
