T5-4.7 E-Paper
Overview
The LILYGO T5-4.7-S3 is a 4.7-inch E-Ink (E-Paper) development board based on the ESP32-S3-WROOM-1-N16R8 (16 MB Flash, 8 MB PSRAM). Integrates capacitive touch (GT911, two-point), PCF8563 RTC, USB-C, Li-Po battery interface (JST-GH 2.0 mm), battery ADC, 40-pin Raspberry Pi-compatible GPIO, onboard TF card slot, and dedicated display drive signals (STV/LE). 2.5D curved design. Ideal for low-power E-Ink applications with touch interaction: electronic labels, smart home displays, portable devices.
