Product interface
接口功能说明
| 接口 | 功能说明 |
|---|---|
| ESP32-S3 | Main control of the display module, controlling on-board and external peripherals |
| MicroSD Interface | Insert a Micro SD card to expand the storage space, such as storing font library, pictures, audio files and other large data content. |
| RGB | LED lights with red, green, and blue colors, controlled by a single IO port. |
| Uart | 1.25mm 4P socket. Can be used for serial port debugging, downloading and communication. An external USB to serial port module is required |
| Battery interface | 1.25mm 2P socket. Used to connect to 3.7V polymer lithium battery, charge the battery through the battery charging management circuit, also used for battery power supply. Note the positive and negative terminals of the interface |
| BOOT key | For entering the download mode or key test. Press and hold this key to power up,
then release to enter the download mode, or after powering up, and hold this key, then press the RESET key, release the RESET key and then release this key, you can also enter the download mode. When it is not necessary enter the download mode, this key can be used as a normal key. |
