Introduction
LILYGO T-Glass is a smart wearable device powered by the ESP32-S3 main controller. It integrates a BHI260AP motion sensor and a JD96013A AMOLED display, offering a 126×126 pixel visible area with touch interaction and high-contrast visual performance.
The device features 4MB Flash and 2MB OSPI PSRAM, providing smooth operation and reliable data storage. Its rich set of functional modules includes a real-time clock (RTC), microphone (supporting MIC_CLOCK/MIC_DATA audio input), vibration feedback (Vibration_Pin), battery level monitoring (BAT_ADC), and a touch button (Touch_Button), making it ideal for fitness tracking, smart notifications, and other interactive applications.
With the LILYGOT-Glass PINMAP interface layout, the board integrates communication protocols such as SPI and I²C, optimizing the hardware arrangement for compact form factors. It is well-suited for lightweight designs like smart glasses or portable wearable devices, combining low power consumption with high performance.

Module Information and Specifications
Description
There are two versions of T-Glass: the initial preview version and the updated T-Glass V2 (which uses an improved prism reflection method). The only difference between them lies in the display method—the hardware remains identical.
T-Wristband and T-Glass share the same hardware, but due to differences in the enclosure design, the viewing area differs.
LilyGO T-Wristband and T-Glass rely on LVGL v8.4.x. Currently, LVGL v9.0 has been released. If you encounter compilation errors, please ensure that your LVGL version is v8.4.x.
The visual display size of T-Wristband and T-Glass differs from the actual screen size. All examples are built upon the LVGL graphics framework. Other graphics libraries such as TFT_eSPI are not supported for these devices.
