What this Stellaris MCU brings to the board
The Texas Instruments LM3S828-IGZ50-C2T is a 32-bit ARM Cortex-M3 microcontroller from the Stellaris® ARM® Cortex®-M3S 800 series, clocked at 50 MHz. On-chip peripherals include an 8-channel 10-bit ADC, a PWM module, brown-out detect, POR, and a watchdog timer — a self-contained compute node for sensor-fusion or motor-control loops on a single 3V supply.
That speed, paired with the 8K x 8 SRAM, keeps interrupt latency predictable for applications like brushless-DC commutation or multi-drop sensor polling.
