4.1 E-Paper Display Characteristics
The 4.7-inch E-Paper display has specific characteristics:
- Due to the flexible nature of the screen, small bubbles may be present in the corners during fitting. This is a normal manufacturing characteristic.
- This version of the E-Paper screen may exhibit a slight yellowish tint.
- Partial refresh of the screen for extended periods can result in residual images (ghosting).

5. Configuració
To begin using your LILYGO T5-4.7-S3 board, follow these setup steps:
- Connectar l'alimentació: Connect the board to a computer using a USB-C cable. The board will power on.
- Initial Firmware Check: The board typically comes with factory test firmware. If the screen displays content, the hardware is likely functioning correctly.
- Instal·leu els controladors: Ensure your computer has the necessary USB-to-serial drivers for ESP32-S3 devices. These are usually automatically installed or can be found on the Espressif weblloc.
- Prepare Development Environment: Install your preferred programming environment (Arduino IDE, VS Code with PlatformIO, or MicroPython). Refer to the official LILYGO GitHub repository for detailed setup instructions and examples: github.com/Xinyuan-LilyGO/LilyGo-EPD47/tree/esp32s3.
5.1 Instal·lació del firmware
To upload new firmware or examples, you will need to put the board into DFU (Device Firmware Upgrade) mode:
- Connect the board to your computer via the USB-C cable.
- Manteniu premut el botó BARRETA botó.
- Mentre encara aguanta el BARRETA button, briefly press the RST botó.
- Allibera el RST botó.
- Allibera el BARRETA botó.
- The board is now in DFU mode and ready for firmware upload via your chosen development environment.
