LILYGO T-Track

Overview

The LILYGO T-Track is a compact development board built around the ESP32-S3R8 processor, featuring an innovative 1.1-inch JD9613 SPI AMOLED display with a 126x294 pixel resolution and full viewing angle capability. The standout feature is an onboard trackball input device, enabling intuitive navigation through menus and interfaces without requiring an external input device.

The board supports the full ESP32-S3 ecosystem with 16MB flash and 8MB PSRAM, along with 2.4 GHz WiFi and Bluetooth 5. The 1.1-inch AMOLED display measures 10.962 x 25.578mm active area and supports 4-wire SPI communication. A 3D antenna is integrated for improved wireless performance.

Boot function is available on PIN IO00. The T-Track is well-suited for wearable devices, compact control panels, remote controls, and any application requiring a small footprint with an intuitive physical input method.
