Adopts ESP32-S3R8 chip with 2.4 GHz Wi-Fi and Bluetooth LE 5.0 support, integrating high-capacity Flash and PSRAM. Features a 1.43-inch AMOLED display capable of smoothly running GUI frameworks such as LVGL. Includes onboard peripherals: RTC chip, QMI8658 6-axis IMU (3-axis accelerometer and 3-axis gyroscope), TF card slot, lithium battery header, and reserved USB, UART, I2C, and GPIO pin headers for strong compatibility and expandability. Suitable for rapid HMI and other ESP32-S3 application development. Equipped with a high-performance Xtensa 32-bit LX7 dual-core processor, up to 240 MHz clock speed. Supports 2.4 GHz Wi-Fi (802.11 b/g/n) and Bluetooth 5.0 (LE), with an onboard antenna. Supports external antenna connection via resistor modification. Built-in 512 KB SRAM and 384 KB ROM; onboard 16 MB Flash and 8 MB PSRAM. The 1.43-inch AMOLED display uses QSPI interface, 466 × 466 resolution, 16.7 million colors, and supports capacitive touch via I2C interface with interrupt capability. Onboard QMI8658 6-axis IMU enables motion gesture detection, step counting, and similar functions. Includes PCF85063 RTC chip with SH1.0 RTC battery header (supports charging) for real-time clock functionality. Features onboard RST and programmable BOOT buttons for custom function development. Includes 3.7 V MX1.25 lithium battery recharge/discharge header. TF card slot supports external storage for images or files. USB Type-C port provides power supply, programming, and debugging capabilities. Onboard UART and I2C SH1.0 4-pin connector, plus two 14-pin 1.27 mm pitch headers supporting multiple GPIO interfaces. CNC-machined metal enclosure with clear labeling on the back for easy identification and portability.
