## Description

## Overview

The LILYGO T-Lora Dual features two Semtech LR1121 multi-band transceivers on a single board, enabling simultaneous sub-GHz (830–940 MHz) and 2.4 GHz LoRa communication. The board supports the ExpressLRS protocol, making it suitable for long-range RC link applications and high-speed telemetry. The dual-radio configuration allows concurrent operation on different frequency bands for increased throughput or redundancy in LoRa mesh networks.
