## Description

## Overview

The LILYGO T3 S3 V1.3 is the hardware revision 1.3 of the T3 S3 ESP32-S3 LoRa development board. It is powered by the ESP32S3FH4R2 chip with 4MB Flash and 2MB PSRAM, providing WiFi and Bluetooth 5.0 connectivity. The board features a 0.96-inch SSD1306 OLED display (128×64, I2C on IO18/IO17) for real-time status readouts. It supports a wide range of LoRa radio modules — SX1262, SX1276, SX1280, and LR1121 — across 433MHz, 868MHz, 915MHz, and 2.4GHz frequency bands, making it highly versatile for regional LoRa deployments. A TF card slot and Reset/Boot buttons are also included. The board is fully compatible with Meshtastic firmware and supports Arduino and PlatformIO development.
