Features

Powerful ESP32-S3: It is a RLCD AIoT development board based on ESP32-S3, adopts high-performance Xtensa 32-bit LX7 dual-core processor, up to 240MHz main frequency. Built-in 512KB Static RAM, 384KB ROM, with integrated 16MB Flash +8MB PS RAM., providing ample computing power for various AIoT applications.

Dual-Mode Communication: It supports 2.4GHz Wi-Fi and Bluetooth 5 (LE) dual-mode communication, with a built-in antenna for stable signal transmission.

4.2inch RLCD Reflective Screen: Onboard 4.2inch RLCD, 300 × 400 resolution, features reflective imaging and no backlight required. Achieving extremely low power consumption, and eliminating glare in bright environments (such as sunlight and indoor lighting), providing clear and transparent display. The display effect is close to that of an e-ink screen, with a faster refresh rate, balancing visual experience and energy efficiency.

Abundant Peripherals + Flexible Expansion: Integrated with audio codec circuit, dual microphones, speaker, SHTC3 high-precision temperature and humidity sensor, TF card slot, R T C header, and Lithium Batt charging and discharging management circuit, etc. Reserved USB, UART, I2C, and multiple GPIO interfaces for easy expansion.

Dual Batt Life Modes for Mobile and Fixed Scenarios: Onboard 18650 Lithium Batt holder and R T C backup Batt header. The R T C backup Batt header supports a rechargeable RTC Batt and dual modes of main Batt power supply and RTC independent power supply. (Note: Batt is not included.)

AI Voice Interaction + Multi-Scenario Adaptability: Supports AI Voice Interaction: Allows access to online large model platforms such as DeepSeek, Doubao, GPT, etc. Widely applicable to DIY desktop smart ornaments, electronic calendars, AI intelligent agents, outdoor screens, and other scenarios.
