800×800 4.0inch Touch LCD Display Wi-Fi 6 ESP32 P4

This compact 4.0 inch touch display with 800×800 pixel resolution is based on the powerful ESP32 P4 microcontroller with integrated Wi Fi 6 support. The built-in IPS LCD panel with ST7701S controller displays vibrant content with 65K colors. The capacitive touchscreen is controlled via an I2C interface and allows precise user input. Power supply and programming are done via USB C. GPIOs and serial interfaces are accessible through side solder pads. The module is ideal for compact graphical user interfaces, controls, or portable IoT devices and can be easily programmed with Arduino or ESP IDF. The manufacturer provides comprehensive documentation, example projects, and the official schematic PDF to assist with commissioning.
