It uses the Tempest-class LM3S9B92 microcontroller with a 32-bit ARM Cortex-M3 core running at 80 MHz.
The 8 MB of SDRAM is connected to the LM3S9B92 through the External Peripheral Interface (EPI) bus.
Tools from Keil, IAR, Code Sourcery and Code Red can be used, with a Stellaris evaluation kit or an ARM Cortex-M3 debugger.
The kit contains the IDM-SBC board, an MDL-ADA2 10-pin to 20-pin adapter, a 128 MB USB flash drive, a 24 V power supply with international plug-set, an Ethernet cable, an 8 Ohm speaker, and a CD with tools, documentation and source code.
