ESP32-S3 1.28inch Double Eye Round LCD AIoT Development Board, Onboard Dual 1.28inch IPS Displays, 240 × 240 Resolution, Dual-core 240MHz Processor, Supports Wi-Fi / Bluetooth 5 Dual IPS Displays | 1.28inch | 240 × 240 | SPI Communication Supports AI speech interaction, onboard TF card slot, Lithium battery header, and DIY connectors, etc. Features The ESP32-S3-DualEye-Touch-LCD-1.28 is an AIoT microcontroller development board based on ESP32-S3 with dual eye LCD displays. Designed for makers and electronics enthusiasts, it supports 2.4GHz Wi-Fi and Bluetooth BLE 5. It integrates high-capacity Flash and PSRAM, onboard dual 1.28inch LCD displays which can smoothly run GUI programs such as LVGL. Additionally, it also integrates a microphone, speaker header, Lithium battery recharge circuit, and reserves a TF card slot and DIY expansion connectors. It is suitable for rapid development based on ESP32-S3 for applications like HMI (Human-Machine Interface), double eye robotic agents, and AI voice-interactive toys. Whether you want to build a robot that can "wink", create an intelligent IoT Interface, design touch-controlled games, or develop futuristic wearable devices, this board is an ideal choice. Equipped with high-performance Xtensa 32-bit LX7 dual-core processor, up to 240MHz main frequency Supports 2.4GHz Wi-Fi (802.11 b/g/n) and Bluetooth 5 (LE), with onboard antenna Built-in 512KB SRAM and 384KB ROM, with onboard 8MB PSRAM and 16MB Flash Onboard dual 1.28inch LCD displays, 240 × 240 resolution, 65K color, optional for touch function Onboard ES8311 audio codec and ES7210 audio ADC chip, equipped with standard microphone and speaker header, supports AI speech interaction Onboard TF card slot for convenient local storage expansion, and supports the storing and reading of data, images, audio files, and more Onboard Lithium battery recharge management module, reserved 3.7V Lithium battery power supply header Onboard SH1.0 14PIN connector, adapting UART, I2C and some IO interfaces, for easy DIY customization Version Options ESP32-S3-DualEye-LCD-1.28without touch function ESP32-S3-DualEye-Touch-LCD-1.28with touch function Capacitive touch Optional for capacitive touch function, controlled via I2C interface for flexible operation and smooth UI interaction, with interrupt support * Only the ESP32-S3-DualEye-Touch-LCD-1.28 version supports touch function. Onboard audio codec chip Supports high-quality audio processing, providing clear and high-quality audio input and output Supports AI Speech Interaction Allows access to online large model platforms such as DeepSeek, Doubao, etc Application Scenarios Robot AI Toy Wireless IoT Application Learning or DIY Creative Project What's On Board ESP32-S3R8 Dual-core processor, up to 240MHz operating frequency 16MB Flash Battery recharge management chip Amplifier chip ES8311 ES7210 Microphone MP1605GTF-Z Power module, supports up to 3.3V 2A output Onboard ceramic antenna IPEX1 connectorfor connecting external antenna, enabled via resoldering an onboard resistor BOOT button GPIO1 function selection resistor soldered on the side near the crystal by default: the GPIO1 pin is used for battery voltage measurement. resoldered to the other side: the GPIO1 connects to the 17. FPC connector, enabling three-screen display function through software modification Battery header MX1.25 2PIN connector, for 3.7V Lithium battery, supports charging and discharging Charge indicator Lithium battery charge indicator, lights up when charging, off when fully charged (the light status is uncertain when the battery is not connected) Speaker header SH1.0 14PIN header 18PIN FPC connector for three-screen display function by resoldering the 12. resistor and modifying the display configuration parameters in the program. when the board is split into two halves, this FPC connector can be linked with 18. FPC connector so that both displays function properly (Note: when the board is split and connected via FPC cable, the RESET button will be unavailable) 18PIN FPC header for connection to the host TF card communication mode selection when the board is split into two halves, switching to SPI mode allows the TF card to be controlled by an external master controller. TF card slot Supports high-capacity TF cards RESET button SH1.0 14PIN cable header for controlling TF card and the LCD display via SPI interface when the board is split into two halves and resoldering 19. resistor to SPI mode Type-C port Outline Dimensions
