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.

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.
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.
