The core controller Core2 is equipped with ESP32-D0WDQ6-V3, featuring two independently controllable Xtensa® 32-bit LX6 processors with a main frequency of up to 240 MHz, supporting Wi-Fi functionality. It has onboard 16MB Flash and 8MB PSRAM, and programs can be downloaded via the USB Type-C interface. Its powerful configuration meets the resource demands of complex applications. The front is equipped with a 2.0-inch integrated capacitive touch screen, providing users with a smoother human-computer interaction experience. The body has a built-in vibration motor, providing haptic feedback and vibration alert functions. The built-in RTC module provides precise timing functionality. The power section is equipped with an AXP192 power management chip that effectively controls the power consumption of the body, with a built-in green power indicator light. The body also includes a microSD slot and a speaker. To ensure higher quality sound effects, it uses a power amplifier chip with an I2S digital audio interface, effectively preventing signal distortion. The left side and bottom of the body have independent power and reset (RST) buttons, and the three dots on the front of the screen are part of the touch screen, which can be programmed to map hot zones as three virtual buttons. The back of the body integrates a small expansion board with a 6-axis IMU sensor and a microphone. Compatibility Issue The vibration motor that comes with Core2 interferes structurally with the Base series bases. To prevent damage to the device, do not stack Core2 with the Base series functional bases.
