K128 CoreS3 ESP32S3 loT development kit

CoreS3 is the third generation of the M5Stack Core series. This kit is based on the ESP32-S3 solution and features a dual-core Xtensa LX7 processor with a clock frequency of 240MHz. CoreS3 is equipped with integrated Wi-Fi functionality that enables seamless connectivity. It has 16 MB of onboard flash memory and 8 MB of PSRAM, providing ample space for storing programs.

CoreS3 offers convenient programming capabilities via its TYPE-C interface, which supports OTG and CDC functions. This enables easy connection to external USB devices and easy firmware flashing. CoreS3 has a 2.0-inch capacitive IPS touchscreen protected by high-strength glass material. In addition, a 30-watt pixel GC0308 camera is integrated at the bottom of the screen, accompanied by an LTR-553ALS-WA proximity sensor to enhance functionality. Power management is handled by the AXP2101 power management chip, which uses a 4-way control loop for efficient power distribution. The entire design is focused on low power consumption. CoreS3 also features a BMI270 6-axis position sensor and a BMM150 magnetometer for precise motion detection. With the integrated TF card slot (microSD) and the BM8563 RTC chip, accurate timing and sleep timer wake-up functions are available.
