The Tuya T5 AI Pixel Screen, powered by a Tuya T5 Wi-Fi/Bluetooth module, includes sensors for temperature, humidity, air quality, light, and motion, all housed on an 85 mm × 75 mm board. The project provides open-source firmware and demo programs for weather displays, spectrum analyzers, and 3D animations, with the ability to generate pixel art from text prompts via AI.", "body_md": "-\n\nWhat if your desk display could respond to voice commands, show AI-generated pixel art, visualize music, display weather, and connect to your smart home — all from a 85 mm × 75 mm open-source board?\n\nIn this tutorial, you'll learn how to build exactly that with the **Tuya T5 AI Pixel Screen**, powered by the **TuyaOpen** open-source framework.\n\nWe'll walk through:\n\nThe Tuya T5 AI Pixel Screen is a compact smart display built around a high-density RGB LED matrix.\n\n| Feature | Details |\n|---|---|\n| Display | 32 × 32 RGB LED matrix |\n| LEDs | 1024 × WS2812 RGB LEDs |\n| Module | Tuya T5 Wi-Fi / Bluetooth |\n| Board Size | 85 mm × 75 mm |\n| Framework | TuyaOpen (fully open source) |\n| Voice | MEMS mic + speaker + audio feedback |\n| Sensors | Temp / humidity / pressure / VOC / light / IMU |\n| Buttons | OK / A / B user buttons |\n| Power | USB-C |\n| Debug | Dual UART via CH342F |\n\nOne sentence summary:\n\nSay something, send data, or trigger an event — and make 1024 pixels come alive.\n\nTuyaOpen is an open-source development framework for building connected IoT devices.

Keep global brightness low:\n\n```\n#define BRIGHTNESS 0.05  // 5% — the default in example code\n```\n\n**Do not exceed 10%** (`0.1`\n\n) for sustained use. This is enough for indoor viewing and keeps the board safe.\n\nConnect a weather API.
