Description
ESP32-S3-DualEye-Touch-LCD-1.28 is a microcontroller development board that supports 2.4GHz Wi-Fi and BT BLE 5. It integrates large capacity Flash and PSRAM, featuring two 1.28inch LCD on board, capable of smoothly running GUI interface programs such as LVGL. Combined with various peripheral interfaces, it is suitable for the quick development of the HMI and other ESP32-S3 applications.

Onboard Resources
- ESP32-S3R8 Dual-core processor, operating frequency up to 240MHz
- 16MB Flash
- Battery charging management chip
- Power amplifier chip
- ES8311 Low-power audio codec chip
- ES7210
- Microphone
- MP1605GTF-Z Power module, supporting up to 3.3V 2A output
- Onboard ceramic antenna
- IPEX1 connector Switching to use the external antenna via resoldering an onboard resistor
- BOOT button
- GPIO1 function modification resistor Default soldered near the crystal, GPIO1 is used for battery voltage measurement. If changed to the position away from the crystal, the signal is routed to the FPC cable, allowing software modification for triple-screen display
- Battery header MX1.25 2PIN connector for 3.7V lithium battery, supports charging and discharging
- Charging indicator When a system battery is connected, it stays on while charging and turns off when fully charged (status indeterminate when no system battery is connected)
- Speaker header
- LCD1-Board SH1.0 14PIN header For programming and log printing
- 18PIN FPC connector While the main board is powered on, adjust the resistor value at position R12 and modify the display configuration parameters in the software to achieve triple-screen display. If the board is broken off, the FPC cable can connect both screens to work properly (note: the RESET button is not available when the board is broken off and connected via FPC cable)
- 18PIN FPC header For connecting the main controller
- TF card communication mode selection When the board is broken off, the side controlling the TF card can be switched to SPI mode, allowing one SPI to control both the TF card and the screen simultaneously
- TF card slot Allows connection of high-capacity TF cards
- RESET button
- LCD2-Board SH1.0 14PIN cable header When the board is broken off, configure the resistor at position R19 for SPI mode, then the 14PIN FPC can be used to control both the TF card and the screen via one SPI bus
- Type-C port
