Story
Description
This powerful 4.0 inch square LCD touchscreen module boasts a vibrant 3.95 inch display with a sharp 480x480 resolution and a sleek 1:1 aspect ratio. The LCD screen uses the ST7701S as the driving IC, and the cable interface is composed of a 40-pin 3-wire SPI+RGB interface. For easier use, we have adopted a standard HD interface, which requires us to equip a HD driving board that uses the RTD2660H as the main controller. The display uses capacitive touch technology and you can enjoy vivid colors and clear images from any angle thanks to its IPS wide-viewing angle technology. It's easy to connect with its plug-and-play HD interface, working seamlessly with popular boards like Raspberry Pi, Beaglebone, and Jetson Nano.
Whether you're building a DIY project, working with embedded systems, creating medical devices, exploring industrial control, designing IoT devices, upgrading your smart home, or bringing any other creative project to life, this display is a fantastic option that delivers a comprehensive solution.
