Overview

LILYGO T-Display is a compact ESP32 development board with a built-in 1.14-inch ST7789V IPS TFT LCD (240 × 135 px). Based on the ESP32 dual-core LX6 processor running at up to 240 MHz, it integrates Wi-Fi 802.11 b/g/n and Bluetooth 4.2 + BLE for wireless connectivity. The board features two programmable push buttons, a battery charging circuit, USB-C programming interface, and exposes a full set of GPIO pins. Its small footprint and integrated display make it popular for wearables, environmental monitors, and IoT dashboards.
