Interface Definition

Interface Function Description

Interface Name Function Description
ESP32-S3 Display module main control,control board peripheral and external peripheral.
MicroSD card slot A MicroSD card is inserted to expand the storage space for storing

large data such as characters, pictures, and audio files.

Serial port 1.25mm 4P connector.It can be used for serial debugging, downloading,

and communication. An external USB to serial port module is required.

BOOT Key Used to enter download mode or key test.

Press and hold this button to power on and release it to enter the download mode.

Alternatively, press and hold this button and then press the RESET button to release the

RESET button and then release this button to enter the download mode.

When you do not need to enter the download mode, this button can be used as a common button.

Type-C Interface Used for module power supply and download programs.

This interface is connected to the one-click download circuit on the module,

which can automatically enter the download mode (without pressing the BOOT key).

RESET Key Used for ESP32 master control and LCD reset, level reset after pressing.
Expand Pin 1.25mm 4P socket, leading out GPIO17/GPIO18 pins.
UART1 & USB 1.25mm 4P socket, leading out four free pins: GPIO17, GPIO18, GPIO19 and GPIO20. GPIO17 and GPIO18 can be used for UART1, while GPIO19 and GPIO20 are compatible with the USB protocol.
SPI Interface 1.25mm 4P socket, designed for connecting external SPI communication devices. This SPI interface is shared with the resistive touch screen and SD card, and can also be used as GPIO.
