It uses an ESP32-S3 controller with a 240 MHz dual-core processor, built-in 16MB Flash and 8MB PSRAM, and native Wi-Fi + BLE wireless communication. The board integrates many built-in peripherals: a rugged 2.0-inch capacitive touch screen, a 0.3 MP camera, proximity sensor, ambient light sensor, and nine-axis IMU; it also provides a microSD card slot, an onboard 1W speaker, dual microphones, power and reset buttons, and is suitable as a direct replacement for the original controller in StackChan AI desktop robots.\u003c\/p\u003e\n\u003cdiv style=\"\n  background: #f3f8ff;\n  border: 1px solid #cfe1ff;\n  border-left: 4px solid #1f6fe5;\n  border-radius: 8px;\n  padding: 14px 16px;\n  margin: 24px 0;\n\"\u003e\n  \u003cstrong style=\"\n    display: block;\n    color: #0d47a1;\n    font-size: 15px;\n    margin-bottom: 6px;\n  \"\u003e\n    Note\n  \u003c\/strong\u003e\n\n  \u003cspan style=\"\n    color: #2c2c2c;\n    font-size: 14.5px;\n    line-height: 1.6;\n  \"\u003e\n    \u003cstrong\u003eCoreS3\u003c\/strong\u003e, \u003cstrong\u003eCoreS3-Lite\u003c\/strong\u003e, and \u003cstrong\u003eStackChan Core\u003c\/strong\u003e differ only in appearance and have no difference in hardware functionality. \u003cstrong\u003eStackChan Core\u003c\/strong\u003e comes preloaded with StackChan firmware at the factory.
