03 / Heterogeneous Dual-Core Co-Processing Bus

Implements a master-slave MCU architecture. The primary ESP32-S3-N16R8 features a 32-bit dual-core Xtensa processor with 16MB Flash and 8MB PSRAM, dedicated to high-bandwidth Wi-Fi/BLE communication and AI edge vision processing. The secondary STM32F103C8T6 (ARM Cortex-M3) runs deterministic, real-time loops for multi-sensor polling, kinematic attitude estimation, and strict interrupt-driven motor control.
