LILYGO T-Mini E paper S3

T-Deck

Introduction

The LILYGO T-MINI E-Paper S3 Kit is a compact (102x24.5x53 mm) multifunctional development board powered by the ESP32-S3FN4R2 dual-core processor with Wi-Fi and Bluetooth 5 support.
Its core highlight is the integration of a low-power 1.02-inch e-paper display (128x80 resolution), the SX1262 LoRa long-range communication module supporting 868/915/923 MHz frequency bands, and 3.7V 18350 lithium battery power supply.
Onboard features include TF card storage expansion, a PCF85063ATL RTC real-time clock, rich GPIO interfaces (SPI/I2C, etc.), and deep-sleep mode support.
It is ideal for building remote environmental monitoring nodes, low-power information display tags, portable data loggers, and other IoT application scenarios.
