Stellaris® LM3S3748 Evaluation Kit
The Stellaris LM3S3748 Evaluation Kit provides a low-cost way to start designing
applications with Stellaris microcontrollers on a compact and versatile evaluation platform.
The evaluation kit design highlights the LM3S3748 microcontroller’s key features including
USB 2.0 full-speed (12 Mbps) controller, Analog-to-Digital Converter (ADC), and serial
interfaces. The LM3S3748 Evaluation Board (EVB) includes connectors for both embedded
USB Host and USB Device operation.
The LM3S3748 EVB can be used either as an evaluation platform or as a low-cost in-circuit
debug interface (ICDI). In ICDI mode, the on-board microcontroller is bypassed, allowing
programming or debugging of an external target.
Power to the EVB can be supplied through the DC jack, the USB Device connector, or the
USB debug interface connector. A small switch controls whether the board is bus-powered
using the USB Device connector or self-powered using the DC jack or USB debug interface
connector.
WARNING: Do not change the power mode switch while power is applied. Doing so
may damage the switch contacts.

Requirements
You have a PC with a USB port, running Microsoft® Windows 2000, XP, or Vista
You have the Stellaris LM3S3748 Evaluation Kit Documentation and Software CD
Initial Board Set-Up
The initial board set-up of the LM3S3748 EVB consists of powering the board and installing
the FTDI drivers that are needed for debug communication.
Powering the EVB
The first step for the initial board set-up is to power the EVB.
1)
Move the USB power mode switch (SW3) to the “SELF” position (see the figure that
follows).
Note:
The switch must be placed in the “SELF” position for the initial board setup to
work correctly.
