Stellaris® Robotic Evaluation Board

Stellaris EVALBOT from Texas Instruments makes experimenting with microcontrollers fun and easy

Texas Instruments - Stellaris® Robotic Evaluation Board Texas Instruments' Stellaris® robotic evaluation board (EVALBOT) is an evaluation platform for the Stellaris LM3S9B92 microcontroller. The board also uses a range of Texas Instruments' analog components for motor drive, power supply, and communications functions. After a few minutes of assembly, the EVALBOT's electronics are ready to run.

When roaming, three AA batteries supply power to the EVALBOT. The EVALBOT automatically selects USB power when tethered to a PC as a USB device or when debugging. Test points are provided to all key EVALBOT signals. Two 20-pin headers enable future wireless communications using standardized Texas Instruments' low-power embedded radio modules (EM boards). Additional microcontroller signals are available on break out pads arranged in rows adjacent to the microcontroller.

The EVALBOT has factory-installed quick start software resident in on-chip flash memory. For software debugging and flash programming, an integrated in-circuit debug interface (ICDI) requires only a single USB cable for debug and serial port functions.

The EVALBOT is available with a Stellaris-specific version of µC/OS-III, “The Real-Time Kernel” by Jean J. Labrosse. This book reveals how a real-time kernel works using Micrium's µC/OS-III and the Stellaris EVALBOT as references. For those who already have the book, the board is available separately.
