LILYGO T-0.99 Inch LCD

Overview

The LILYGO T-0.99 Inch LCD is a compact display module featuring an ultra-narrow 40x160 pixel TFT panel driven by the GC9D01 controller. The long, thin form factor (8.6 x 29.8 mm) makes it ideal for status bars, wristwatch displays, and narrow instrument panels where a conventional square or rectangular display would not fit.

The module uses a 4-line SPI interface and is available with two connector options: a GH1.25mm 8-pin connector and a standard 2.54mm 10-pin header, providing flexibility for breadboard prototyping and compact PCB integration. An immersion gold process and sub-black material give it a premium appearance. A 150mm GH1.25 extension cable is included.

This display is the same panel used in the LILYGO T-Keyboard product and is compatible with LILYGO ESP32-C3 and ESP32-S3 boards through standard SPI GPIO assignment.
