CrowPanel Advance 4.3inch ESP IDF Course V13
Product Model: CrowPanel-Advance-4.3-HMI-ESP32-S3-AI-Powered-IPS-Touch-Screen
Hardware Version: V1.3
Number of Lessons: 5 lessons
Development Platform: ESP-IDF v5.5.4 + ESP32-S3
Learning Path: ESP-IDF Environment Setup -> HTTP MP3 -> LVGL LED -> DHT20 Temperature and Humidity Display -> SD Card BMP Image Display
1. Course Overview¶
This course is designed for the CrowPanel Advance 4.3-Inch HMI ESP32-S3 Screen V1.3 and uses native ESP-IDF projects for development. The course starts with ESP-IDF development environment installation and serial port verification, then covers HTTP MP3 network audio playback, LVGL LED control, DHT20 temperature and humidity data acquisition and display, and reading BMP images from an SD card for on-screen display.
The 4.3inch version uses an 800 x 480 IPS touchscreen and ESP32-S3. It is designed for AI HMI and smart touchscreen applications, and is suitable for learning how to integrate large-format display, audio playback, sensor acquisition, and storage-based display features in native ESP-IDF projects.
The ESP-IDF course content and lesson links are shared across the 4.3-inch, 5.0-inch, and 7.0-inch versions. This guide focuses on the 4.3inch V1.3 version.
