M5Core2 is the second generation core device in the M5Stack development kit series, which further enhances the functions of the original generation of cores. It is a powerful and user-friendly development board with the following features:

  • MCU: Equipped with an ESP32-D0WDQ6-V3, featuring dual core Xtensa® 32-bit 240Mhz LX6 processors that can be controlled separately.
  • Memory: Onboard 16MB Flash and 8MB PSRAM.
  • Interface: USB TYPE-C interface for charging, program downloading, and serial communication.
  • Display: 2.0-inch integrated capacitive touch screen with three programmable capacitive buttons on the front.
  • Power Management: Managed by an AXP192 power management chip (upgraded to AXP2101 in Core2 V1.1), which effectively controls power consumption. It includes a built-in green LED power indicator for battery level notification. The battery capacity is 390mAh, providing longer power duration than the previous model.
    • For Core2 V1.0: Configure CONFIG_BSP_PMU_AXP192
    • For Core2 V1.1: Configure CONFIG_BSP_PMU_AXP2101
  • Audio: I2S digital audio interface power amplifier chip to prevent signal distortion, along with a built-in speaker.
  • Expansion: Retains a TF-card (microSD) slot, and an expansion board on the back with a 6-axis IMU sensor and a microphone.
  • RTC Module: Built-in RTC module for accurate timing, with a dedicated battery for RTC power supply in Core2 V1.1. Additional Features: Built-in vibration motor for haptic feedback, independent power, and reset buttons on the left side and bottom of the base.

Core2 V1.1 Enhancements

Core2 V1.1 is an iterative version of Core2 with the following upgrades and additional features:

  • Power Management: Uses the AXP2101 power management chip for enhanced power control.
  • Indicators: Built-in blue power indicator light for specific functions or status indications.
  • RTC Battery: Dedicated battery for RTC power supply for accurate timing.
  • User Interaction: Enhanced touch screen experience with programmable virtual buttons for diverse human-machine interaction.
