CoreS3-SE is a lightweight version of the third-generation CoreS3 main controller 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 240 MHz, and integrates (2.4G) Wi-Fi connectivity. The board is equipped with 16MB Flash and 8MB PSRAM. Programs can be downloaded via the USB Type-C interface, which supports OTG and CDC functions, making it convenient for connecting external USB devices and flashing firmware.
The front side features a 2.0-inch capacitive touch IPS display, with a panel made of high-strength glass material. The power system uses the AXP2101 power management chip along with four power path control circuits, adopting an overall low-power design. A built-in microSD card slot is included. The board integrates a BM8563 RTC chip, providing accurate timekeeping and sleep–timed wake-up functions.
For audio output, it uses a high-fidelity 16-bit I2S amplifier chip AW88298, with a built-in 1W speaker. Audio input is handled by an ES7210 audio codec chip combined with dual-microphone input. On the side of the device, there are independent power and reset (RST) buttons, along with a built-in delay circuit; long-pressing the reset button allows entry into program download mode. This finished product is suitable for IoT development, various DIY projects, smart home control systems, and industrial automation control systems.

Power Management
CoreS3-SE uses the AXP2101 power management chip together with the AW9523B IO expansion chip to control the direction of power input and output. Please refer to the pin states of BUS_OUT_EN and USB_OTG_EN below to set the power input and output directions. For specific settings, please refer to CoreS3 Power Management Example.
There are hardware differences between CoreS3-SE and CoreS3. Code sections in the library involving Camera, Proximity sensor, IMU, and Magnetometer are not compatible with CoreS3-SE.
