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. |
