M5Stack CoreS3 ESP32S3 loT Development Kit
CoreS3 is the latest addition to the M5Stack Core series, showcasing a powerful ESP32-S3 solution. It features a dual-core Xtensa LX7 processor running at 240 MHz and includes built-in Wi-Fi for easy connectivity. The device comes with a generous 16 MB of onboard flash memory and 8 MB of PSRAM, providing ample storage for your applications.
The CoreS3 offers flexible programming options via its USB Type-C interface, which supports OTG (On-The-Go) and CDC (Communication Device Class) functionalities. This makes it simple to connect to external USB devices and facilitates firmware updates. With a 2.0-inch capacitive touch IPS screen protected by durable glass, it is designed for user friendliness. Additionally, it features a 30W pixel camera GC0308 and a proximity sensor (LTR-553ALS-WA) for enhanced functionality.
Power management is controlled by the AXP2101 power management core chip, which utilizes a 4-way power flow control loop for efficient power distribution, emphasizing low energy consumption. The CoreS3 also includes a 6-axis attitude sensor BMI270 and a magnetometer BMM150 for accurate motion tracking. It also features an onboard TF card (microSD) slot and the BM8563 RTC chip for precise timing and sleep-timer wake-up functionalities.
Designed for superior audio performance, the CoreS3 is equipped with a high-fidelity 16-bit I2S power amplifier chip AW88298 and a built-in 1W speaker for clear sound reproduction. For sound input, it incorporates the ES7210 audio decoding chip along with two microphones.
The device is equipped with a dedicated power button and a reset (RST) button, featuring a self-built delay circuit. Users can enter program download mode easily by long-pressing the reset button.
The CoreS3 kit includes the DinBase Base, which provides versatile mounting options such as Din rail, wall, and screw fixtures. It can be powered via an external DC 12V source (compatible with 9V to 24V) or by an internal 500mAh lithium battery. The DinBase also offers multiple prototype locations, allowing for project customization and expansion.
Ideal for IoT development, the CoreS3 is perfect for various DIY projects, smart home systems, and industrial automation control systems.
