Overview
The LILYGO T5s 2.7 inch E-Paper is a feature-rich ESP32 development board combining wireless connectivity with an ultra-low-power 2.7-inch monochrome e-paper display. It integrates a MAX98357A Class-D I2S amplifier and an ICS43434 MEMS microphone for audio-capable IoT applications. A 500mA battery management IC with short-circuit, overcharge, and overflow protection manages LiPo charging via USB. Four LEDs provide real-time battery status. The board exposes GROVE and GPIO headers, a TF card slot for expanded storage, and a power button supporting single-click start and double-click shutdown. Compatible with the Arduino IDE and the GxEPD2 / LilyGo-T5-Epaper-Series libraries.
