## Description

## Overview

The LILYGO T-Beam Supreme is the flagship upgrade to the popular T-Beam series, built around the ESP32-S3FN8 with 8MB PSRAM for enhanced processing power. It retains the T-Beam's defining combination of LoRa (SX1262), GPS, WiFi, and BLE while adding a QMI8658 6-axis IMU for motion-aware applications.

The board is available with either an L76K or u-blox GNSS module, covering multiple frequency variants (433 MHz, 868 MHz, 915 MHz, 920 MHz, and 144–148 MHz for aircraft tracking). SoftRF firmware is pre-flashed on select variants, enabling immediate use as an aircraft transponder receiver compatible with ADS-B and FLARM protocols.

The upgraded ESP32-S3 enables Meshtastic mesh networking at higher throughput, while the IMU adds orientation and motion detection for mobile tracking nodes, drone telemetry, and wildlife monitoring applications.
