T5AI-Board Development Kit
The T5AI-Board is a voice-and-screen development board built on the Tuya T5-E1-IPEX Wi-Fi and Bluetooth combo module. It carries two microphones and one speaker for voice interaction, and breaks out the full module pinout so you can add an LCD-and-camera stack module or wire your own peripherals. Use it to prototype AIoT voice and display applications with the standard TuyaOpen workflow.
Software build configurationโ
The board-level configuration file defines key functional components, such as peripheral drivers, pin mapping, board support packages (BSP), and third-party libraries. By using the pre-configured board-level configuration files for the development board, you can significantly reduce the workload of hardware adaptation and driver development, thus improving development efficiency.
:::tip Interested in developing new peripherals? Configuration features:
- To add a new peripheral, you can write drivers directly at the application layer. BSP drivers are primarily intended for peripherals integrated on the board.
- Peripheral requirements might vary across applications. You must adjust the configuration files based on specific needs.
- Depending on your application requirements, you might need to configure different third-party library parameters.
- It is recommended to use the initial config file as the base template for board-level configuration and extend or modify it as needed for your project. :::
How to enable configurations? Refer to CLI - tos.py Development Tool > config choice.

Hardware overviewโ
The T5AI-Board is based on the T5-E1-IPEX module, an embedded Wi-Fi and Bluetooth combo module developed by Tuya. The board carries 2 microphones and 1 speaker, supporting voice recognition and playback to enable voice interaction.
Through the I/O connectors on the board, you can stack an LCD display module to add touchscreen and camera capture capabilities. You can also design your own LCD screen using the I2C, SPI, 8080, or RGB interface.
