A USB A to B cable for connecting the OSIF to your PC

An Open Source InterFace is a USB to I2C converter.

This interface converts USB signals to the fast (400khz) I2C interface.

With schematics, hardware layouts, and source code, it is the perfect debugging and control device.

Examples:
Controlling PCF8574 I2C to IO interface
Temperature sensing via LM75
Any I2C interface that conforms to I2C specification
Controlling an OpenServo

The OSIF is designed to control the OpenServo servo motor controller, but will serve as a generic USB to I2C interface.
