Core2 V1.1 is an iterative version of Core, with upgraded power IC and a continuation of the classic design of Core2. It is a powerful and user-friendly development board. Core2 V1.1 is equipped with ESP32-D0WDQ6-V3, featuring two independent Xtensa® 32-bit LX6 processors with a clock frequency of up to 240MHz. It supports WiFi functionality and has onboard 16MB Flash and 8MB PSRAM, and supports program downloading via the TYPE-C interface. Its strong configuration can meet the requirements of complex applications.
Core2 V1.1 is equipped with a 2.0-inch integrated capacitive touch screen. The three dots on the front of the screen are part of the touch screen. Users can set the hot zone mapping as three virtual buttons through programming, enabling diverse human-machine interaction experiences. Additionally, Core2 V1.1 has a built-in vibration motor for haptic feedback and vibration alert functionality.
Core2 V1.1 has an integrated RTC module and a dedicated battery for RTC power supply, providing accurate timing functionality. Furthermore, the AXP2101 power management chip effectively controls the power consumption of the device. Core2 V1.1 also has a built-in blue power indicator light, which can be used to implement specific functions or status indications according to the user's application needs. Core2 V1.1 is also equipped with a MicroSD card slot, speaker, and a high-quality I2S digital audio interface power amplifier chip. The expansion board on the back of the device integrates a 6-axis IMU sensor and a microphone, providing additional functionality and possibilities.
