Stellaris® LM3S2965 Evaluation Board
The Stellaris® LM3S2965 Evaluation Board is a compact and versatile evaluation platform for the
Stellaris LM3S2965 ARM® Cortex™-M3-based microcontroller. The evaluation kit demonstrates a
complete controller area network (CAN) using two Stellaris microcontrollers. The main evaluation
board (EVB) configures a Stellaris LM3S2965 microcontroller as a CAN host. A small CAN device
board, linked with a ribbon cable, uses a Stellaris LM3S2110 microcontroller. The function of each
board is fully configurable in software.
You can use the board either as an evaluation platform or as a low-cost in-circuit debug interface
(ICDI). In debug interface mode, the on-board microcontroller is bypassed, allowing for
programming or debugging of an external 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 for CAN. The kit also includes extensive source-code examples, allowing you to
start building C code applications quickly.
