Stellaris® LM3S1968 Evaluation Board
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.
