CoreS3 ESP32S3 IoT Development Kit

CoreS3 is the third generation of the M5Stack development kit series. Its MCU adopts the ESP32-S3 solution, dual-core Xtensa LX7 processor, the main frequency is 240 MHz, comes with Wi-Fi function, and the onboard 16 M Flash and 8 M PSRAM. It can download the program through the USB Type-C® interface, support OTG and CDC functions, and facilitate external USB devices and flashing firmware. The front is equipped with a 2.0 inch capacitive touch IPS screen, and the panel is made of high-strength glass material. A 0.3-megapixel camera GC0308 is built into the bottom of the screen with proximity sensor LTR-553ALS-WA. The power supply part adopts the AXP2101 power management core chip and 4-way power flow control loop, and the overall adopts a low power consumption design. There is an onboard 6-axis attitude sensor BMI270, magnetometer BMM150, TF-card (microSD) card slot, and a BM8563 RTC chip providing accurate timing and sleep-timer wake-up function. It features a high-fidelity 16-bit I²S power amplifier chip AW88298 for sound output, and the fuselage has a built-in 1 W speaker. In terms of sound input, ES7210 audio decoding chip and dual microphone input is employed. On the side of the fuselage, there is an independent power button and restart (RST) button, delay circuit, and long-press reset button for entering the program download mode. The CoreS3 set comes with a DinBase Base by default, which is convenient for din rail, wall, and screw fixing. It can be powered by an external DC 12 V (support 9 V ~ 24 V) or internal 500 mAh lithium battery. DinBase reserves multiple proto locations for users to DIY. This finished product is suitable for scenarios such as Internet of Things (IoT) development, various DIY project development, smart home control systems, and industrial automation control system.
