Development Board
Dual IPS Displays | 1.28inch | 240 × 240 | SPI Communication
Supports AI speech interaction, onboard TF card slot, Lithium battery header, and DIY connectors, etc.
The ESP32-S3-DualEye-Touch-LCD-1.28 is an AIoT microcontroller development board based on ESP32-S3 with double eye LCD displays, designed for makers and electronics enthusiasts, supporting 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 the quick development based on ESP32-S3 such as 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.

- 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 connector
for 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
