KLAYERS ESP32-S3 4.2inch RLCD AIoT Development Board, AI Voice and Environmental Sensors,no BAT

• Powerful AIoT Core with Rich Connectivity: Driven by the ESP32-S3 dual-core processor (up to 240MHz) with 16MB Flash and 8MB PSRAM, this board features robust 2.4GHz W F and BT 5 (LE) connectivity. It comes with ample interfaces (USB, UART, I2C, GPIO) and a TF card slot for seamless IoT development and expansion.
• Unique 4.2inch Reflective LCD for Eye-Friendly Displays: The onboard 4.2-inch RLCD (300x400) offers a paper-like, glare-free viewing experience without a backlight, significantly reducing eye strain. It combines the comfort of e-paper with a faster refresh rate for smoother interactions and lower power consumption.
• Integrated AI Voice Interaction System: Equipped with a dual-microphone array, audio codec, and a speaker, the board supports advanced audio algorithms like noise reduction and echo cancellation. This enables accurate far-field/near-field voice wake-up, voice recognition, and AI voice interaction for smart device applications.
• Comprehensive Sensing & Power Management: Features a high-precision SHTC3 temperature & humidity sensor for environmental monitoring and a PCF85063 RTC chip for precise timekeeping. It includes flexible power options with an 18650 battery holder, charging circuitry, and a dedicated rechargeable RTC backup battery header for reliable operation.
• All-in-One Development Platform for Diverse Projects:聽This integrated board is ideal for rapidly prototyping smart desktop ornaments, electronic calendars, voice-controlled devices, and environmental monitors. Its out-of-the-box components and sensors make it perfect for DIY learning, product development, and creating energy-efficient IoT solutions.
