T5-4.7 E-Paper S3 Lite

Overview

The LILYGO T5-4.7-S3 series offers two models based on ESP32-S3-WROOM-1-N16R8 (16 MB Flash, 8 MB PSRAM): Pro and Lite. The Lite edition removes GPS and LoRa to reduce cost for pure display applications (e-books, photo frames, weather stations), and upgrades to AG (anti-glare) glass for better outdoor visibility and a warm backlight for comfortable extended reading. Both share the same 4.7-inch EDO47TC1 E-Ink display (540 × 960), GT911 two-point capacitive touch, PCF8563 RTC, TF card slot, and Raspberry Pi 40-pin GPIO expansion.

PlatformIO

1. Install Visual Studio Code and Python
2. Search for and install the PlatformIO IDE extension in VS Code
3. Open the LilyGo-EPD47 project folder
4. Open platformio.ini, uncomment one src_dir = xxxx line (only one active at a time)
5. Click ✓ to compile, connect via USB-C, click → to upload

Arduino

1. Install Arduino IDE
2. Install Arduino ESP32 and add boards manager URL: https://espressif.github.io/arduino-esp32/package_esp32_index.json
3. Copy library folders from the project libraries directory to your Arduino libraries folder
4. Open the example .ino file
5. In Tools → Board, configure:

FAQ

• Q. Are the Lite and Pro editions code-compatible? A. Yes — core display, touch, RTC, and other basic functions are fully compatible between editions.

• Q. What are the benefits of AG glass and warm backlight? A. AG (anti-glare) glass reduces reflections and improves outdoor visibility. Warm backlight provides a more paper-like reading experience, reducing eye strain during long sessions.

• Q. Arduino IDE prompts to upgrade libraries? A. Do not upgrade — stay with the tested library versions.

• Q. Upload fails? A. Hold BOOT (IO0), press RST, release RST, release BOOT, then click Upload.
