The M5Stack Core2 is the second generation core device in the M5Stack development kit series, which further enhances the functions of the original generation of cores.


Lithium Battery Shipping: Due to courier restrictions, this product can only be shipped within England/Wales. With this item in your cart your shipping options will be limited and may cost more than our usual rates. Why?
The MCU is an ESP32 model D0WDQ6-V3 and has dual-core Xtensa® 32-bit 240Mhz LX6 processors that can be controlled separately. Wi-Fi is supported as standard and it includes an onboard 16MB Flash and 8MB PSRAM, USB TYPE-C interface for charging, downloading of programs and serial communication, a 2.0-inch integrated capacitive touch screen, and a built-in vibration motor.

The M5Core2 also features a built-in RTC module which can provide accurate timing. The power supply is managed by an AXP192 power management chip, which can effectively control the power consumption of the base and a built-in green LED power indicator helps to notify the user of the battery level. The battery capacity has been upgraded to 390mAh, which can power the core for much longer than the previous model.

The M5Core2 retains the TF-card (microSD) slot and speakers. However, in order to ensure higher quality sound output, the I2S digital audio interface power amplifier chip is used to effectively prevent signal distortion. There are independent power and reset buttons on the left side and bottom of the base.

The 3 icons on the front of the screen are capacitive buttons which are programmable. There is a small expansion board on the back of the base with a 6-axis IMU sensor and microphone. The development platform and programming language supported by M5Stack Core2: Arduino, UIFlow (using Blockly, MicroPython language) No matter what level of your development and programming skills, M5Stack will help You gradually turn your ideas into reality.

Power Management

Operation:

  • Power on: One click the power button on the left
  • Power off: Long press the left power button for 6 seconds
  • Reset: Click the RST button on the bottom side

USB drive

Before using, please go to the download page to download the USB driver that matches your operating system, and install it.

Note: The Core2 currently has two CP2104/CH9102F A USB chip versions, users can install the drivers (CH9102 and CP210x) that are compatible with two ICs at the same time to ensure that the device drivers work normally.

Extensions

To stack M5Core2 with M5 modules, you need to remove/eliminate the battery bottom of Core2; If you wish to keep I2S Mic, IMU and Battery functions, an M5GO Bottom2 is required.**The CP2104 chip interface is reserved on the PCB of CORE2 to interface with the lithium battery.

The vibration sensor of the M5Core2 and M5 Base series are incompatible in mechanical design. Please do not stack them together.

Some of the screen edges will have touch non-linearity problems, you can try to use the M5Tool to upgrade the screen firmware to solve this problem.
