Description

Core2 v1.1 is the iterative version of the second-generation host in the M5Stack development kit series, further enhancing the functionality based on the original generation host. It features a power management chip solution of AXP2101+INA3221, offering more comprehensive hardware functions, adding an RTC battery to meet the needs of low-power applications and precise timing functions. Its core controller is equipped with an ESP32-D0WDQ6-V3, featuring two independently controllable Xtensa® 32-bit LX6 processors, with a main frequency of up to 240Mhz, supporting WiFi functionality, and onboard 16MB Flash and 8MB PSRAM. Programs can be downloaded via the TYPE-C interface, and the robust 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 tactile feedback and vibration alert functions. The built-in RTC module and battery dedicated to RTC power supply offer precise timing functions. The power section features an AXP2101 power management chip for effective control of body power consumption, with a built-in blue power indicator light. Additionally, the body is equipped with a TF-card (microSD) slot and speaker. To ensure higher quality sound effects, an I2S digital audio interface amplifier chip is used to effectively prevent 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 expansion board on the back of the body integrates a 6-axis IMU sensor and microphone.
