Overview
LILYGO T5 e-Paper Basic is an ESP32-S3 development board for a large-format parallel e-paper display. The official repository contains PlatformIO examples for the display, XL9555 I/O expander, SD card, Wi-Fi, AXP2602 battery gauge, factory testing, and an employee badge application. The repository version table lists a 4.7-inch-class 960 x 540 e-paper display. The factory-test application also contains a 1216 x 684 panel configuration selected with FACTORY_TEST_PANEL_1216X684.

FAQ
| Problem | Check |
|---|---|
| Display is blank | Confirm the EPD cable, USB power, board definition, and panel resolution configuration. |
| Display has lines or severe ghosting | Power-cycle the board, check the panel cable, and allow the full refresh to finish. |
| SD card is not detected | Use a FAT32 card and check MOSI GPIO38, SCK GPIO39, MISO GPIO40, CS GPIO47, and XL9555 P05 card detect. |
| Wi-Fi scan finds no network | Use a 2.4 GHz access point; ESP32-S3 does not scan 5 GHz-only networks. |
| Buttons do not respond | Check I2C on GPIO2/GPIO3 and the XL9555 connections on P00 to P04. |
| Upload fails | Enter download mode manually and retry with a data-capable USB cable. |
