Description The StackChan Core controller is the replacement main controller for the M5Stack StackChan robot. Its ESP32-S3 dual-core processor, 16 MB Flash, 8 MB PSRAM, 2.4 GHz Wi-Fi, and Bluetooth Low Energy provide the computing and connectivity needed for interactive robot projects. A 2-inch capacitive touch display, 0.3 MP camera, proximity and ambient-light sensor, 9-axis motion sensing, microSD slot, 1 W speaker, and two microphones are integrated into the compact controller. The StackChan Core controller is designed for replacing the original controller in a compatible StackChan main unit. Notice: The StackChan App connects only to an original StackChan controller installed in the standard StackChan, the Remote Controller Kit, or this replacement controller. Flash the StackChan user firmware before use. The app cannot connect to CoreS3, CoreS3-SE, or CoreS3-Lite controllers.
