M5Stack CoreS3 Lite ESP32S3 IoT Dev Kit

The M5Stack CoreS3 Lite is a powerful IoT development board based on the ESP32-S3 with Dual-Core-LX7 at 240 MHz, 16 MB Flash, and 8 MB PSRAM. A 2.0"" IPS display with capacitive touch makes operation intuitive and enables clear visualizations. The integrated 0.3 MP camera (GC0308) and a proximity and ambient light sensor (LTR-553ALS-WA) open up exciting HMI and recognition applications. A 6-axis IMU (BMI270) and a 3-axis magnetometer (BMM150) are available for motion detection and orientation. Power supply AXP2101 and RTC BM8563 enable energy management, real-time functions, and timed wake-up in low-power operation. A 16-bit I2S amplifier (AW88298) with 1 W speaker and ES7210 audio codec with dual microphone allow for voice and audio interactions. Data can be logged or resources expanded via the microSD card slot. USB-OTG allows for flexible peripheral connectivity and convenient flashing. The magnetic back simplifies attachment to whiteboards, machine housings, or shelves. With a compact form factor, robust design, and rich interfaces, the CoreS3 Lite is ideal for prototyping, teaching, and smart control. Thanks to extensive libraries and examples, getting started with Arduino or UIFlow projects is particularly fast.
