Evaluation Kit Texas Instruments EKS-LM3S1968

Detailed Description

The Stellaris LM3S1968 Evaluation Board is a compact and versatile evaluation platform for the Stellaris LM3S1968 ARM Cortex-M3-based microcontroller.

The evaluation kit design  highlights the LM3S1968 microcontroller's peripherals and its Hibernation module.

A 3V lithium battery, included in the kit, supplies power to the Hibernation module and maintains data and real-time clock information for about two years in the absence of USB power.

You can use the EVB either as an evaluation platform or as a low-cost in-circuit debug interface (ICDI). In debug interface mode, the on-board microcontroller is disabled, allowing connection of the debug signals to an external Stellaris microcontroller target. The kit is also compatible with high-performance external JTAG debuggers.This evaluation kit enables quick evaluation, prototype development, and creation of application-specific designs using the LM3S1968's broad range of peripherals. The kit also includes extensive source-code examples, allowing you to start building C code applications quickly.
