Overview
The LILYGO T-Display is a compact ESP32 development board built around the Espressif ESP32-PICO-D4 System-in-Package (SiP), which integrates dual-core Xtensa LX6 processors at 240MHz, 4MB flash, WiFi, and Bluetooth all in a 7×7mm package. The onboard 1.14-inch ST7789V IPS LCD renders 135×240 pixels at 260 PPI, delivering sharp color graphics in a minimal footprint.
Two programmable buttons, a battery voltage detection circuit (GPIO34), and a JST LiPo connector make the T-Display a popular choice for portable gadgets, smart badges, and handheld IoT devices. The CH9102 USB-to-serial bridge provides reliable programming and debug output without additional drivers on modern systems.
Programming support includes the Arduino IDE and MicroPython, backed by an extensive library on GitHub. The board ships with I2C (GPIO21/22), SPI, UART, and ADC pins broken out on 0.1-inch headers, and has passed CE, FCC, UKCA, and MIC certifications for international use.
