Description

CoreS3 Lite is a programmable ESP32-S3 IoT controller built for interactive products, smart-home systems, robotics, and edge-device prototypes. It combines a 240MHz Xtensa 32-bit LX7 dual-core processor with 16MB Flash and 8MB PSRAM, giving developers a compact controller with enough memory for display, sensor, audio, and camera workflows.

The front of CoreS3 Lite integrates a 2.0-inch capacitive-touch IPS display, a 0.3MP GC0308 camera, and an LTR-553ALS-WA proximity and ambient-light sensor. Inside the device, a BMI270 6-axis IMU, BMM150 3-axis magnetometer, BM8563 RTC, AXP2101 power-management IC, microSD slot, 1W speaker, ES7210 dual-microphone audio codec, and AW88298 I2S amplifier support richer interaction designs.

With 2.4GHz Wi-Fi, USB OTG, a 200mAh LiPo battery, and a magnetic back cover for quick mounting, CoreS3 Lite is suitable for desktop voice assistants, educational robots, industrial status monitors, and compact control panels.

Notes

Products containing magnets may interfere with the BMM150 magnetic-field sensor and cause abnormal readings. When using CoreS3 Lite with M5 controllers or accessories that contain magnets, remove the magnets when needed and avoid placing the BMM150 near strong magnetic fields.

Other Content

The schematic and model files help confirm display, camera, microSD, audio, RTC, sensor, HY2.0-4P, and M5-BUS connections before custom integration.

CoreS3 Lite can be developed through UiFlow2 or Arduino IDE, while PlatformIO and ESP-IDF resources support lower-level firmware work.

For deployed devices, the magnetic back cover, onboard battery, RTC, and power-management IC help simplify mounting, timed wake-up, and portable operation.
