ESP32-P4-WIFI6-Touch-LCD-4B

ESP32-P4-WIFI6-Touch-LCD-4B

This series is a high-performance development board based on the ESP32-P4 chip. This series adopts a dual-core plus single-core RISC-V architecture design, featuring a built-in 4inch 720 × 720 resolution IPS touch display. It supports rich human-machine interaction interfaces, including MIPI-CSI with an integrated image signal processor (ISP), and USB OTG 2.0 HS port for high-speed connections. The ESP32-P4 chip integrates a digital signature peripheral and a dedicated key management unit to ensure data and operational security. It is designed for high performance and high security applications, and fully meets the higher requirements of embedded applications for human-computer interface support, edge computing capabilities and IO connection features.

Development Tools​

Each of these two development approaches has its own advantages, and developers can choose according to their needs and skill levels. Arduino is suitable for beginners and non-professionals because they are easy to learn and quick to get started. ESP-IDF is a better choice for developers with a professional background or high performance requirements, as it provides more advanced development tools and greater control capabilities for the development of complex projects.

warning

Due to the limited support for ESP32-P4 on the Arduino platform, ESP-IDF is currently recommended for development.

  • ESP-IDF, or full name Espressif IDE, is a professional development framework introduced by Espressif Technology for the ESP series chips. It is developed using the C language, including a compiler, debugger, and flashing tool, etc., and can be developed via the command lines or through an integrated development environment (such as Visual Studio Code with the Espressif IDF plugin). The plugin offers features such as code navigation, project management, and debugging, etc. We recommend using VS Code for development. For the specific configuration process, please refer to the Working with ESP-IDF. The tutorial also provides relevant example programs for reference.
