USB Interface Adapter Evaluation Module User's Guide

Abstract

This EVM serves as an interface adapter or a bridge between a host PC and one or multiple targeted devices through a standard type-A to mini-B USB cable. The communication between the USB interface adapter and the host PC is through USB, while the communication between the USB interface adapter and the target device or devices is through an inter-integrated circuit (I²C), general-purpose inputs and outputs GPIOs, or both. The bridge converts communication transactions between the USB and I²C/GPIO.
