## Description

## Overview

The LILYGO LoRa3, also known as the T3 LoRa32 V1.6.1, is a feature-rich ESP32-based development board that integrates LoRa long-range radio communication alongside Wi-Fi 802.11 b/g/n and Bluetooth 4.2. It uses the SX1278 transceiver for 433 MHz or the SX1276 for 868/915 MHz frequency bands, providing a LoRa sensitivity of -148 dBm and data rates up to 300 kbps. The board includes a 128×64 pixel OLED display, TF card slot, SMA antenna connector, and a JST GH 1.25mm 2-pin battery connector. The CH9102 USB-to-serial chip handles programming via Micro USB. It supports fast wake-up, frequency hopping, automatic gain control, automatic frequency correction, and a highly configurable data packet handler. Compatible with Meshtastic, MeshCore, and Paxcounter firmware.
