Product Overview

The ULCD-43DT is a powerful 4.3-inch TFT LCD Intelligent Display, powered by the 4D systems DIABLO16 processor. An extensive range of hardware and software peripherals have been integrated into the design, to give the user freedom to adapt the module to suit almost any application. Features include a 4.3-inch TFT 480 x 272 touch screen display, audio, micro-SD card connector, an expansion port along with a series of GPIO, I²C, SPI and UART serial communications. The uLCD-43D/DT/DCT serves as the perfect solution to be deployed at the forefront of any product design, requiring a brilliance of colour, animation or images on a 4.3-inch widescreen display. The uLCD-43D (DIABLO16) range was designed to be a drop in replacement for the uLCD-43P (PICASO) range and features the same mechanical dimensions for ease of upgrading. There are however some electrical differences.
