Description
Core2 for AWS is the reference hardware kit for AWS IoT Kit – a prescriptive learning program from AWS which 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 micro controller, which features dual Xtensa 32-bit LX6 cores and a main frequency 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. Onboard RTC module provides 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.

Driver Installation
CP2104 version)/CP34X (for CH9102 version) driver compressed package. After decompressing the compressed package, select the installation package corresponding to the number of operating systems to install. (If you are not sure of the USB chip used by your device, you can install both drivers at the same time. During the installation process of CH9102_VCP_SER_MacOS v1.7, an error may occur, but the installation is actually completed, just ignore it.) When using it, if If the program cannot be downloaded normally (the prompt is overtime or Failed to write to target RAM), you can try to reinstall the device driver.| Driver name | Applicable driver chip | Download link |
