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.

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.
