Two versions exist: without protective cover glass and with protective cover glass. This listing is the version without protective cover glass. - ESP32-S3R8 processor and wireless: high-performance Xtensa 32-bit LX7 dual-core processor up to 240 MHz. 2.4 GHz Wi-Fi (802.11 b/g/n) and Bluetooth 5 LE with onboard antenna. - Memory and storage: 512 KB SRAM and 384 KB ROM onboard; 16 MB Flash and 8 MB PSRAM. - Display and touch: onboard 1.46-inch IPS LCD display, 412×412 resolution, 16.7M colors, wide viewing angle. Capacitive touch panel controlled via I2C with interrupt support. - Audio and voice: onboard audio input and output with high-quality processing. Includes an offline voice model for device control via shortcut commands. Supports peripheral expansion via UART, GPIO and I2C interfaces. - Sensors and timing: onboard QMI8658 6-axis IMU (3-axis accelerometer and 3-axis gyroscope) for motion detection and steps counting. Onboard PCF85063 RTC chip with a reserved RTC battery header (supports charging) for RTC functionality. Programmable PWM and BOOT buttons for easy custom function development. - Storage and power management: onboard TF card slot for extended storage and fast data transfer, supporting data recording and media playback. Flexible clocking and multiple power modes enable low power consumption in different scenarios. GPIO pins can be mapped to various function interfaces for convenient customization and development. - Use scenarios: a compact smart home control panel with local UI and offline voice commands; portable data logging and media playback device with expandable storage; educational robotics, DIY kiosks, or handheld interfaces requiring touch input, motion sensing, and configurable I/O.
