The M5Stack 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 M5Stack Core2 ESP32, 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" colour 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.
