Description
CoreS3-SE is a lightweight version of the third-generation CoreS3 host in the M5Stack development kit series. Its main controller adopts the ESP32-S3 solution, with a dual-core Xtensa LX7 processor, running at 240 MHz, featuring built-in (2.4G) Wi-Fi, onboard 16MB Flash and 8MB PSRAM. Programs can be downloaded via the USB Type-C interface, supporting OTG and CDC functionality for convenient connection of USB devices and firmware flashing. The front is equipped with a 2.0-inch capacitive touch IPS screen with a high-strength glass panel.
The power supply section uses an AXP2101 power management chip along with 4-way power flow control circuits, with an overall low-power design.
Onboard microSD card slot. Onboard BM8563 RTC chip provides accurate timing and sleep-timer wake-up functionality.
Audio output uses a high-fidelity 16-bit I2S amplifier chip AW88298, with a built-in 1W speaker. Audio input uses the ES7210 audio decoder chip + dual microphone inputs.
Independent power button and reset (RST) button are located on the side of the device. With a built-in delay circuit, holding the reset button enters download mode.
This product is suitable for IoT development, various DIY project development, smart home control systems, and industrial automation control systems.

Product Comparison
Compared with CoreS3, CoreS3-SE does not include a camera (GC0308), proximity sensor (LTR-553ALS-WA), IMU (BMI270), or magnetometer (BMM150). CoreS3-SE adopts a medium gray color different from the black-gray of CoreS3, with the touch area of the glass panel extending to the camera position. The DinBase base originally included in the CoreS3 kit is also removed.
