The M5Stack CoreS3 SE IoT Controller (w/o Battery Bottom) is a streamlined version of the third-generation CoreS3 host within the M5Stack development kit series. It is powered by the ESP32-S3 solution, featuring a dual-core Xtensa LX7 processor operating at 240 MHz. This controller integrates built-in Wi-Fi and offers substantial memory capacity with 16MB Flash and 8MB PSRAM.
The device supports program downloads via a USB Type-C interface, which also facilitates OTG and CDC functionalities for seamless USB device connections and firmware updates. It boasts a 2.0-inch capacitive touch IPS screen protected by a high-strength glass panel, ensuring durability and clarity.
The power management is handled by an AXP2101 chip, which, along with a 4-way power flow control circuit, ensures efficient energy use. Additional features include a microSD card slot and a BM8563 RTC chip for precise timing and sleep-timer wake-up functions. Audio capabilities are enhanced by a high-fidelity 16-bit I2S amplifier chip and a built-in speaker, complemented by an ES7210 audio decoder chip with dual microphone inputs.
The device is equipped with an independent power button and a reset button, the latter featuring a built-in delay circuit for entering download mode. This IoT controller is ideal for IoT development, DIY projects, smart home control systems, and industrial automation control systems.
