Interface Function Description:
- ESP32-S3: display module main control, control board mounted peripherals and external peripherals.
- Micro SD card slot: insert a Micro SD card (not included) to expand storage space, such as storing large data contents such as word libraries, images, audio files, etc.
- RGB tri-color light: LED lights with three colors: red, green, and blue, requiring only one IO control to indicate status.
- Serial port: 1.25mm 4P. Can be used for serial debugging, downloading, and communication. An external USB to serial port module (not included) is required.
- Battery interface: 1.25mm 2P, used for connecting 3.7V lithium polymer batteries. Charging the battery through the battery charging management circuit can also be used for battery power supply. Pay attention to the positive and negative terminals of the interface.
- BOOT button: used for entering download mode or key testing. Press and hold this button to power on, then release it to enter download mode. Alternatively, after powering on, hold down this button and then press the RESET button, after releasing the RESET button, you can also enter download mode by releasing this button again. When there is no need to enter download mode, this button can be used as a regular button.
- Type-C interface: used for module power supply and program download. 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).
