BMT ESP32 LVGL WiFi Bluetooth 3.5" TFT Touch Display Board

The BMT ESP32 LVGL 3.5-inch TFT Development Board is a high-performance embedded IoT and GUI development platform built around the powerful ESP32-WROOM-32 dual-core microcontroller. Designed for advanced human-machine interface (HMI) applications, it combines WiFi, Bluetooth, a full-color touchscreen display, and rich peripheral support into a single compact module.

Featuring a 3.5-inch 320×480 RGB TFT display with 16-bit color depth (65K colors), this board delivers sharp, vibrant visuals suitable for industrial dashboards, smart control systems, and interactive IoT applications. The integrated resistive touch panel enables precise user input for menu navigation, control interfaces, and real-time monitoring systems.

Powered by LVGL (Light and Versatile Graphics Library), the board supports the creation of modern, responsive, and visually rich graphical user interfaces. LVGL enables smooth animations, widgets, and efficient memory usage, making it ideal for embedded systems with limited hardware resources.

The module also includes a wide range of integrated peripherals such as a TF card slot for storage expansion, speaker driver circuit, RGB LED control, sensor interfaces (including DHT11 support), and multiple I/O expansion ports. It supports development through Arduino IDE, ESP-IDF, MicroPython, and Mixly, making it highly flexible for developers of all skill levels.
