4Discovery 3.5″ Integrated Wall/Panel Mount Display

The 4Discovery is designed to be mounted to a standard light switch flush/mounting box, which enables quick and easy installation in to a wall, and can just as easily be mounted into an enclosure or panel or directly onto the wall, enabling a wide range of customers to take advantage of this display product.

Driving the display and peripherals is the DIABLO16 processor, a very capable and powerful chip which enables stand-alone functionality, programmed using the 4D Systems Workshop 4 IDE Software. The Workshop IDE enables graphic solutions to be constructed rapidly and with ease due to its design being solely for 4D graphics processors.

The 4Discovery has an array of features including a 3.5″ 320×480 TFT LCD Display, Resistive Touch, micro-SD memory storage, 16MB of Flash Memory storage, Real Time Clock, 2 wire RS485 Interface which can act as Master or Slave with additional changeover wire, Optional WiFi, Optional Crypto Authentication security chip for secure transmissions, and a switch-mode power supply enabling a wide input voltage range, along with many more features.

This 4Discovery can be programmed to store 16MB worth of graphics, images, videos, data on the external flash, which may be desirable so a microSD card is not required. Additional images/data can be stored on the microSD card, or the microSD card can be used to upgrade the application running on the 4Discovery or update the external Flash memory. The options
