4. Einrichtung
4.1 Montage
The T-Embed comes as a shell kit, requiring assembly of the circuit board within the provided enclosure. Carefully align the circuit board with the mounting points inside the shell. Ensure all connectors and the display are properly seated before securing the enclosure. Refer to the official GitHub repository for detailed assembly instructions and shell files wenn nötig.
4.2 Erstes Einschalten
The T-Embed supports dual power supply options:
- USB Typ C: Connect a standard USB Type-C cable to the port on the device and to a 5V power source (e.g., computer USB port, USB wall adapter).
- Li-Po-Akku: Connect a compatible Li-Po battery to the JST 1.25mm connector. Ensure correct polarity. The device includes battery voltage detection on IO04.
Upon successful power-up, the 1.9-inch LCD display should illuminate, and the device will begin its boot sequence.
4.3 Software Setup and Programming Environment
To develop applications for the T-Embed, you will need to set up a programming environment. The device supports both Arduino-IDE and ESP-IDF.
- Install Arduino IDE or ESP-IDF: Download and install your preferred development environment.
- Install ESP32-S3 Board Support: Follow the instructions for adding ESP32-S3 board support to your chosen IDE.
- Obtain T-Embed Libraries and Examples: Access the official LILYGO T-Embed GitHub repository for necessary libraries, example code, and detailed programming guides.

5. Bedienung
5.1 Anzeige und Navigation
The 1.9-inch LCD display serves as the primary visual interface. Navigation and interaction are typically managed through the integrated macro knob (encoder) and associated buttons (Reset, Boot). The specific functionality of the display and controls will depend on the firmware loaded onto the T-Embed.
5.2 Programmierung und Anpassung
The T-Embed is a development board, meaning its core functionality is defined by the code you upload. It can be programmed to perform a wide range of tasks, such as:
- Custom control panel for smart home devices
- Macro keyboard or shortcut device
- IoT sensor data display
- Audio processing (using the microphone and speaker slot)
- Network monitoring tool
Refer to the LILYGO GitHub repository for example projects and detailed documentation on how to program the ESP32-S3 and utilize the T-Embed's peripherals.
