LILYGO T-TV

Overview

The T-TV is a unique and charming programmable desktop device from LILYGO that takes the form of a miniature transparent television. It features a 1.54-inch blue transparent OLED display housed in a PC+ABS shell, creating a retro aesthetic that stands out on any desk.

Factory firmware comes pre-loaded with a desktop clock, classic airplane and chess games, animation playback, and host sleep functions. All features are controllable via the included infrared remote control. A TTP223 capacitive touch button provides an alternative input method.

The device runs on ESP32, providing WiFi and Bluetooth connectivity for custom firmware development. The board includes a 105mAh battery for portable operation, a USB Type-C port for charging and programming, and a 2.0 4-pin I2C/UART expansion interface with 3.3V output for connecting additional peripherals.

Two variants are available: with shell (K115, $34.69) and without shell (H560, $26.34). The GitHub repository (LilyGo-Tv-lite) provides sample code for custom applications.

Firmware Compatibility

The T-TV can be programmed using Arduino IDE or ESP-IDF. The factory firmware source and example projects are available in the LilyGo-Tv-lite GitHub repository.
