M5Stack Core2 AWS ESP32 IoT Development Kit

Core2 for AWS is the reference hardware kit for AWS IoT Kit – a prescriptive learning program from AWS that makes it easy and cost-effective to learn how to build IoT applications using AWS services. It comes equipped with a Microchip ATECC608 Trust&GO pre-provisioned secure element, in addition to the existing features of the standard M5Stack Core2 and M5GO Bottom2. The Core2 for AWS is a feature-rich, plug-and-play extensible, and secure hardware kit for learning and building a wide range of IoT applications.

The Core2 for AWS comes with an ESP32-D0WDQ6-V3 microcontroller, which features dual Xtensa 32-bit LX6 cores and a main frequency of up to 240Mhz, with 2.4GHz Wi-Fi. Comes with 8MB PSRAM and 16MB flash on board.

The main unit is equipped with a 2.0-inch capacitive touch screen that provides a smooth and responsive human-machine interface. The built-in vibration motor can be used to provide haptic feedback or alerts. The board RTC module provides an accurate time of day. Power is supplied through an AXP192 power management chip, to monitor and control power attributes of the device. The included TF card slot supports microSD cards up to 16GB. The on-board speaker is paired with an I2S digital audio interface power amplifier chip to reduce signal distortion and provide clearer audio output. There are independent physical power and reset (RST) buttons on the sides of Core2 for AWS, with 3 programmable touch buttons on the front of the screen.

The M5GO Bottom2 for AWS adds additional features and security for IoT applications. The MPU6886 provides 6-axis internal IMU and temperature, the SPM1423 digital microphone captures audio for recording or creating voice applications, 10 individually programmable RGB LEDs via SK6812 to create customized and animated light effects, a 500mAh lithium-ion battery provides power on the go, the onboard Microchip ATECC608 Trust&GO crypto-authentication chip is pre-provisioned with secure keys to simplify connectivity to AWS and accelerate cryptographic computation. The CP2104 chip interface is reserved on the PCB of Core2 for AWS to interface with the lithium battery.

Power Management

Operations:
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

Extensions

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