Introduction:
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.
