M5Stack StackChan Core

M5Stack StackChan Core is the main controller for the StackChan robot and is intended for use as a mainboard replacement. This core uses an ESP32-S3 controller with a 240MHz dual-core processor, built-in 16MB flash and 8MB PSRAM, and native Wi-Fi® + BLE wireless communication. The board integrates built-in peripherals, including a rugged 2.0-inch capacitive touch screen, a 0.3MP camera, a proximity sensor, an ambient light sensor, and a nine-axis IMU. This board also provides a microSD card slot, an onboard 1W speaker, dual microphones, power, and reset buttons. The StackChan core is suitable as a direct replacement for the original controller in StackChan AI desktop robots.
