Core2 v1.3

SKU:K010-V13

Description

Core2 v1.3 is a highly integrated controller designed for IoT applications. It features the ESP32-D0WDQ6-V3 core with an Xtensa dual-core 32-bit LX6 processor running at 240 MHz. The board includes 16MB of Flash, 8MB of PSRAM, and supports 2.4 GHz Wi-Fi. This version is an iteration of Core2 v1.0, retaining the AXP192 power management IC while upgrading the 6-axis IMU on the rear expansion board to a BMI270, which improves pose detection accuracy and overall performance without compromising system architecture or compatibility. For human-machine interaction, the device features a 2.0" color capacitive touchscreen. The three dot-shaped touch zones on the front panel are programmable and can be mapped to three virtual buttons. A built-in vibration motor provides tactile feedback. For storage and audio, the board includes a microSD card slot and a speaker, with audio output delivered via an I2S digital interface through the NS4168 amplifier to minimize distortion and enhance sound quality. The device also integrates an RTC real-time clock IC and a 500mAh lithium battery. The rear expansion board incorporates a BMI270 6-axis IMU and a microphone, supporting motion sensing and audio capture. This product is well-suited for IoT terminals, human-machine interaction devices, pose detection, and embedded multi-function development applications.

Notes

• The built-in vibration motor of Core2 v1.3 has a structural interference with Base series bases. To prevent damage to the device, do not stack Core2 v1.3 with any Base series expansion base.
• When stacking Core2 v1.3 with M5 modules, you will need to remove the battery bottom of Core2 v1.3. If you need to retain the I2S microphone, IMU, and battery functions of the base while stacking additional modules, it is recommended to use the M5GO Bottom2.
• Some screen edges may exhibit touch non-linearity. You can try using M5Tool to upgrade the screen firmware to resolve this issue.

USB Driver

Download and install the CH9102 USB serial (VCP) driver from the table below according to your operating system. When installing CH9102_VCP_SER_MacOS v1.7, the installer may display an error message, which is typically a false positive — the driver is usually installed correctly and you can safely dismiss the prompt and proceed. If firmware flashing or downloading fails, times out, or returns errors such as Failed to write to target RAM, try reinstalling the driver or switching to a different USB cable or port.
