StackChan Core is the main controller for the StackChan robot and is intended for mainboard replacement. 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.
