ESP32 3.5 Inch 320x480 Resolution HMI Touch Screen TFT-LCD Smart Display Module with 16 Learning Leons for / LVGL

Description

Elecrow ESP32 Display 3.5-inch module is a powerful HMI touch screen with a 320*480 resolution LCD display. It uses the ESP32-WROOM-32 module as the main control proceor, with a dual-core 32-bit LX6 microproceor, integrated WiFi and Bluetooth wirele functions, a main frequency of up to 240MHz, providing powerful performance and versatile applications, suitable for IoT application devices and other scenes.

The module includes a 3.5-inch LCD display and a driver board. The display screen uses resistive touch technology and comes with a resistive touch pen, ing the screen usage more flexible. In addition, the board has reserved a TF card slot, multe peripheral interfaces, USB interface, speaker interface, battery interface, etc., providing more expansion poibilities. It supports development environments such as IDE, Espreif IDF, Lua RTOS, and Micro Python, and is compatible with the LVGL graphics library. This enables developers to not only customize their own UI interfaces but also to create interesting projects quickly and easily, greatly shortening the development cycle.

The ESP32 Display 3.5-inch module is suitable for a wide range of scenes such as automotive HMI, equipment, industrial control, power, civil electronics, automation, , new energy, and IoT application devices. Its various interfaces and expansion functions e it able to meet the needs of different fields, providing users with a more comprehensive solution.
