Introduction

1 Introduction
The EV2400 EVM interface board enables an IBM-compatible or other type PC (with the required driver
for its particular platform) to communicate with the Texas Instruments SMBus and I
gauges via a Universal Serial Bus (USB) port. In addition to this board, PC software is required to interpret
the gas gauge data to complete the evaluation system.
1.1 Features
• Fully powered from the USB port
• Optional 5-V port for powering high-power voltage drivers (future upgrade)
• Complete interface between the USB and SMBus or I
• Expansion port for future upgrades
1.2 Kit Contents
• EV2400 circuit module
• Standard USB cable
