4D Systems SK-UVGA-LLL

The uVGA-III module is a compact and cost-effective standalone VGA graphics engine powered by the PICASO graphics processor. With its powerful graphics, text, image, and animation capabilities, along with numerous other built-in functions, it delivers QVGA/VGA/WVGA graphics solutions for any embedded project. Depending on the programming environment selected when using 4D Systems' Workshop4 IDE software, users can program the uVGA-III module either as a standalone device or as a slave to an external host controller. When used as a standalone device, users have full control over all available resources on the hardware platform, such as serial ports, uSD memory cards, and I/O pins. This eliminates the need for an external host controller/processor to drive the uVGA-III module via serial commands. It gives users complete control over the hardware module, enabling rapid development of practical applications. When the uVGA-III is used as a serial slave to an external host controller, the host sends specific commands to the uVGA-III via its serial UART to generate the desired user display interface. The uVGA-III features a remote VGA connector that can be disconnected from the PCB. This remote VGA connector provides flexible mounting and connection options when using the uVGA-III. A 30-pin header is available on the back of the PCB, unpopulated from the factory, but the header is supplied with the module. Users can solder it if additional I/O and communication functionality is required. Wires can also be soldered directly to the PCB if needed.
