M5Stack CoreS3 SE ESP32S3 IoT Development Kit

The M5Stack CoreS3 SE is the lightweight version of the third generation CoreS3 main unit from the M5Stack development kit series. It is based on the ESP32-S3 solution and features a dual-core Xtensa LX7 processor with a main frequency of 240 MHz. The device offers integrated 2.4G WiFi functionality and has 16 MB FLASH and 8 MB PSRAM on board. Programs can be downloaded via the TYPE-C interface, which supports OTG and CDC functions, facilitating the connection of USB devices and firmware burning. The front is equipped with a 2.0-inch capacitive touch IPS screen protected by high-strength glass. Power is supplied by the AXP2101 power management chip and a 4-way power flow control circuit, ensuring an overall low power consumption. The device features a MicroSD card slot and a BM8563 RTC chip for precise timekeeping and sleep timer wake-up functions. It has a built-in 1-watt speaker and uses a high-resolution 16-bit I2S amplifier chip for sound output. For sound recording, there is an ES7210 audio decoder chip with dual microphone inputs. The device is suitable for IoT development, various DIY project developments, smart home control systems, and industrial automation systems.
