The M5CoreS3 SE is a lightweight version of the third-generation CoreS3 main unit in the M5Stack development kit series. It is powered by the ESP32-S3 solution, featuring a dual-core Xtensa LX7 processor with a main frequency of 240MHz, and comes with built-in (2.4G)WiFi functionality. It has onboard 16MB FLASH and 8MB PSRAM; programs can be downloaded via the TYPE-C interface, which supports OTG and CDC functions, making it convenient to connect USB devices and burn firmware. The front is equipped with a 2.0-inch capacitive touch IPS screen, with a high-strength glass panel. Difference Between M5Stack CoreS3 and M5Stack CoreS3 SE The power supply part uses the AXP2101 power management chip and 4-way power flow control circuit, designed for low power consumption overall. It has an onboard MicroSD card slot and a BM8563 RTC chip that provides precise timing and sleep-timer wake-up functions. For sound output, it uses a high-fidelity 16-bit I2S amplifier chip AW88298 and has a built-in 1W speaker. For sound input, it uses an ES7210 audio decoding chip with dual microphone input. The device body has an independent power button and reset (RST) button on the side, with a built-in delay circuit. Long pressing the reset button enters program download mode. This product is suitable for IoT development, various DIY project development, smart home control systems, and industrial automation control systems. Version comparison Compared to the M5CoreS3, the M5CoreS3 SE does not feature a camera (GC0308), proximity sensor (LCR-553ALS-WA), IMU (BMI270), or magnetic compass (BMM150). The M5CoreS3 SE uses a medium grey number different from the black-grey number of the M5CoreS3, and the glass panel touch area extends to the camera position. The DinBase base with the original M5CoreS3 kit was removed.
