The M5Stack Core2 ESP32 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 processorsfrom 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 aMicroSD 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
Lithium Battery Shipping: Due to courier restrictions, this product can only be shipped within the United Kingdom. With this item in your cart your shipping options will be limited and may cost more than our usual rates. Why?
Power Management
