## Description

## Overview

The LILYGO T3 S3 E-Paper combines the ESP32-S3FH4R2 microcontroller with an SX1262 LoRa radio and a 2.13-inch DEPG0213BN e-paper display (250×122 pixels). It is designed for long-range IoT sensor nodes that require a local status display without continuous power draw. The board runs on USB or a 3.7V LiPo battery with an onboard power switch, supports TF card storage, and exposes reset and boot buttons. Three frequency variants are available: 868MHz, 915MHz (both with SX1262 LoRa), and a 2.4GHz variant without a PA stage. Compatible with Arduino IDE, ESPHome, and Meshtastic firmware. Suitable for field data logging, environmental monitoring, and off-grid LoRa mesh applications.
