LILYGO T-Track ESP32-S3 board combines 1.1-inch AMOLED display with trackball

After the T-Display-S3 AMOLED board, LILYGO has launched another ESP32-S3 board with an AMOLED display named the T-Track that features a smaller 1.1-inch AMOLED display and a trackball that allows the user to navigate any menu or user interface shown on the display.

The rest of the board’s specifications are very similar with an ESP32-S3R8 dual-core chip with 8MB PSRAM providing WiFi and BLE connectivity, a 16MB SPI flash for storage, two rows of pins for up to 18x GPIOs, a Qwicc connector for module expansion, and support for USB-C charging and a LiPo battery for power.

ESP32-S3 board AMOLED Display Trackball

The ESP32-S3 board works with PlatformIO (Arduino code) and LILYGO provides sample code that works with LVGL graphics library to test the AMOLED display and includes functions for WiFi and the trackball on GitHub, as well as the PDF schematics.

The T-Track board is currently sold on Aliexpress for$20.88 including shipping.
