Original M5Stack Core2 v1.1 ESP32 IoT Development Kit – PartsCountry

Description

The Core2 V1.1, following its predecessor the Core2, comes with a familiar design but includes some key updates. This development board is user-friendly and powerful, equipped with an ESP32-D0WDQ6-V3 chip. This chip features two 32-bit LX6 processors from Xtensa, capable of speeds up to 240MHz, and supports WiFi. The board has 16MB Flash and 8MB PSRAM for storage, and uses a TYPE-C interface for program downloads, making it suitable for various projects.

This model boasts a 2″ capacitive touch screen, which includes three dots that can be programmed as virtual buttons for different interactive experiences. The Core2 V1.1 also has a built-in vibration motor for feedback and alerts.

Additionally, the Core2 V1.1 has an integrated RTC module for keeping accurate time, powered by a dedicated battery. Its power consumption is managed by the AXP2101 chip. There’s a blue power indicator light on the board, which can be programmed for different functions or indicators as needed. Other features include a MicroSD card slot, a speaker, and a quality I2S digital audio interface with an amplifier chip. On the back, there’s an expansion board with a 6-axis IMU sensor and a microphone.

Note: To stack Core2 V1.1 with M5 modules, you’ll need to remove/eliminate the battery bottom of Core2 V1.1. If you wish to keep I2S Mic, IMU and Battery functions, a M5GO Bottom2 is required

Revision History

As of 07/02/2024, we are now stocking V1.1, which has the following changes:

• Power Management Scheme: While the original Core2 uses the AXP192 power management scheme, the Core2 v1.1 has upgraded to a combination of AXP2101 and INA3221. This change is identifiable in the differing IDs of AXP192 and AXP2101, which the program uses to distinguish between the two versions.
  
• Power Indicator Color: The Core2 features a green power indicator, whereas the Core2 v1.1 has changed this to blue.
  
• RTC Chip Power Supply: The Core2 v1.1 adds a dedicated battery for the RTC (Real-Time Clock) chip to ensure accurate timing even when the main power is off
