 **Architecture**
-The ESP32's architecture is built upon the Xtensa LX6 microprocessor core, which provides two 32-bit RISC-V cores clocked at up to 240 MHz. This dual-core design enables simultaneous execution of both CPU-intensive and I/O-intensive tasks, improving overall system performance. The chip also features an advanced memory hierarchy with multiple banks of RAM and flash storage.
