## Description

## Overview

The LILYGO T-Glass is a unique wearable development platform that integrates an ESP32-S3 microcontroller with a 1.1-inch full-color LTPS AMOLED display into a glasses-prism form factor for head-up display applications. The display uses the JD9613 driver delivering 294×126 pixel resolution with vivid colors.

The compact board includes a microphone for voice commands, an RTC for timekeeping, and a touch button for interaction — making it self-contained for notification, navigation, and data display applications. The device is designed to mount into eyeglass frames, projecting information directly into the wearer's field of view.

Powered by the ESP32-S3FN4R2 with WiFi and BLE, the T-Glass can receive real-time data from smartphones or IoT servers. It is ideal for developers building custom AR glasses, cycling heads-up displays, navigation aids, or wearable notification systems.
