CrowPanel ESP32 HMI 7.0-inch Display¶

Description¶

CrowPanel ESP32 Display 7.0-inch module is a powerful HMI touch screen with 800*480 resolution LCD display. It uses the ESP32-S3-WROOM-1-N4R8 module as the main control processor, with a dual-core 32-bit LX6 microprocessor, integrated WiFi and Bluetooth wireless 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 7.0-inch LCD display and a driver board. The display screen uses a capacitive touch technology and the board has reserved a TF card slot, multiple peripheral interfaces, USB interface, speaker interface, battery interface, etc., providing more expansion possibilities. It supports development environments such as Arduino IDE, Espressif IDF, Lua RTOS, and Micro Python, and is compatible with the LVGL graphics library, supports openHASP. Additionally, it provides 16 learning tutorials and a wealth of open-source learning materials. 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 CrowPanel ESP32 Display 7.0-inch module is suitable for a wide range of scenes such as automotive HMI, medical equipment, industrial control, power, civil electronics, automation, GPS, new energy, and IoT application devices. Its various interfaces and expansion functions make it able to meet the needs of different fields, providing users with a more comprehensive solution.

Module: DIS08070H
