Description

The M5CoreS3 SE is a streamlined version of the third-generation CoreS3 main unit, engineered for IoT developers and makers. It leverages the ESP32-S3 SoC, providing a dual-core 240MHz LX7 processor with robust 2.4GHz Wi-Fi connectivity, substantial 16MB flash storage, and 8MB PSRAM for data-intensive tasks. The USB-C interface supports OTG and CDC functions, facilitating easy firmware uploads and direct connection of USB peripherals.

Power management is handled by the AXP2101 chip, which orchestrates a 4-way power flow control circuit to minimize overall consumption, making it suitable for portable applications. The integrated BM8563 RTC chip provides accurate timing and enables advanced sleep modes with timer-based wake-up. The device combines a high-fidelity audio pipeline with a 1W speaker and dual microphones, enabling projects involving sound recognition, playback, or voice control.

Key Features

  • Powered by ESP32-S3 with dual-core Xtensa LX7 CPU @ 240MHz and integrated 2.4GHz Wi-Fi.
  • Equipped with a 2.0-inch, 320x240 resolution capacitive touch IPS LCD screen protected by high-strength glass.
  • Advanced AXP2101 power management IC for efficient energy use and low-power sleep modes.
  • Comprehensive audio subsystem: 16-bit I2S amplifier (AW88298) driving a 1W speaker and ES7210 codec for dual microphone input.
  • Onboard BM8563 Real-Time Clock (RTC) for precise timing, alarms, and sleep timer wake-up functionality.
  • Expandable storage via a dedicated MicroSD card slot for data logging and asset storage.
  • USB Type-C port supporting both OTG (host) and CDC (serial) functions for flexible connectivity.
  • Supported by M5Stack's UIFlow block-based IDE and the Arduino framework for rapid development.

Frequently Asked Questions

How do I program the M5Stack CoreS3 SE and what frameworks are supported?

You can program the CoreS3 SE using the Arduino IDE with the ESP32 board package installed or M5Stack's graphical UIFlow (based on MicroPython). For low-level control, Espressif's ESP-IDF is also supported. Connect via the USB-C port, select the correct COM port and board (e.g., 'M5Stack CoreS3'), and upload your sketch. The device also supports OTG, allowing it to act as a USB host for peripherals.

What is the power consumption in sleep mode and how do I use the RTC wake-up?

When powered by its internal battery connector (approx. 4.2V), the CoreS3 SE consumes about 104.64 µA in standby mode. The onboard BM8563 RTC chip enables deep sleep with timer-based wake-up. In your code, you can configure the RTC alarm using the provided libraries, then put the ESP32-S3 into deep sleep. The AXP2101 PMIC manages the power rails to ensure minimal current draw during these periods.

Can I use the dual microphones for voice recognition or recording?

Yes, the dual microphone inputs, processed by the ES7210 audio codec, are designed for stereo recording and voice pickup. You can access the audio data via the I2S interface in your firmware. This setup is suitable for implementing voice command features using libraries like ESP-ADF or for recording environmental audio to the MicroSD card for later analysis.
