Description

Core2 for AWS is a dedicated kit for AWS IoT learning projects. It consists of the M5Stack Core2 main control unit and the M5GO-Bottom For AWS expansion base, with an additional custom integration of the ATECC608 Trust&GO hardware encryption, making it an ideal kit for IoT learning and secure project development.

The main control unit Core2 is equipped with the ESP32-D0WDQ6-V3, featuring two independently controllable Xtensa® 32-bit LX6 processors with a clock speed of up to 240MHz, supporting WiFi functionality. It comes with 16MB Flash and 8MB PSRAM, and programs can be downloaded via the TYPE-C interface. The robust configuration meets the resource demands of complex applications. The front features a 2.0-inch integrated capacitive touchscreen, providing a smoother human-machine interaction experience. The device includes a built-in vibration motor for tactile feedback and vibration alerts. The built-in RTC module offers precise timing functions. The power section is equipped with the AXP192 power management chip, effectively controlling power consumption, and includes a green power indicator. The device also features a TF-card (microSD) slot and a speaker. To ensure higher-quality sound, an I2S digital audio interface amplifier chip is used, effectively preventing signal distortion. The left side and bottom of the device have independent power and reset (RST) buttons. The three dots on the front of the screen are part of the touchscreen and can be programmed as three virtual buttons.

M5GO-Bottom For AWS is an expansion base specifically designed for this custom model. The base integrates an MPU6886 six-axis motion sensor, a digital microphone (SPM1423), and a 500mAh lithium battery. It provides two HY2.0-4P expansion interfaces, exposing commonly used ADC/DAC/UART pins for connecting various sensors. The sides of the base feature 10 programmable RGB LEDs (SK6812), paired with frosted light-transmitting material, providing a soft and comfortable lighting effect. The bottom uses a pogo pin magnetic charging interface. When attached to the charging base, current flows safely into the internal battery via the built-in TP4057 charging chip. In addition to charging, the pogo pin interface exposes the main control I2C bus, allowing for magnetic attachment of external expansions. The base includes built-in magnets and a LEGO-compatible hole design on the back, enabling seamless integration with other LEGO structures. The PCB of Core2 for AWS reserves interfaces for the CP2104 chip and the lithium battery. The AWS custom model embeds the ATECC608 hardware encryption chip, enhancing the security of IoT communication at the hardware level.

Expansion Module/Compatibility

The built-in vibration motor of M5Core2 may interfere with the structure of the M5 Base series base. To prevent damage, do not stack M5Core2 with the M5 Base series functional base.
Some edges of the screen may have non-linear touch issues. You can try using M5Tool to update the screen firmware to resolve this issue.
