Interface Definition

Interface Function Description

Interface Name Function Description
ESP32-WROOM-32E Module 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.

RGB LED Contains red, green, blue three colors of LED lights, each light can be controlled by IO,

used to indicate the status.

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.

Battery Interface 1.25mm 2P connector.Used to connect 3.7V polymer lithium battery,

charge the battery through the battery charge management circuit, can also be used for battery power supply. Note the positive and negative terminals of the interface.

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 the input pin 1.25mm 2P connector. IO35 and IO39 are two input-only IOs that are used to access input signals.
Speaker Interface 1.25mm 2P connector. Used to access the speaker to play audio.
SPI peripheral interface 1.25mm 4P connector. For external connection to devices that use IIC communication.

It can be used as ordinary IO.

I2C peripheral interface 1.25mm 4P connector. For external connection to devices that use IIC communication.

It can be used as ordinary IO.
