  • Standalone Graphics Engine
  • VGA Interface
  • QVGA/VGA/WVGA Compatible
  • VGA Graphics Engine - PICASO

The uVGA-III module is a compact and cost effective standalone VGA graphics engine powered by the PICASO graphics controller. It can provide QVGA/VGA/WVGA graphics solution to any embedded project with its powerful graphics, text, image, animation and countless more features built inside the module.

The PICASO works as a standalone device. It allows the user to take complete control of all available resources on the uVGA-III hardware platform such as the Serial Ports, uSD memory card, I/O pins, etc. This eliminates the need for an external host controller/processor to drive the uVGA-III module via serial commands. It provides the user complete control over the hardware module allowing them to quickly develop practical applications.

Programmed with 4D Systems Workshop 4 IDE Software, the uVGA-III could be the ideal embedded VGA graphics solution for your project.
