The VK204-25 is an intelligent VFD display designed to decrease development time by providing an
instant solution to any project. With the ability to communicate via serial RS-232/TTL and I 2 C protocols,
the versatile VK204-25 can be used with virtually any controller. The ease of use is further enhanced by
an intuitive command structure to allow display settings such as brightness, and baud rate to be software
controlled. Additionally, up to thirty-two custom charaters, such as character sets for bar graphs, medium
and large numbers, may be stored in the non-volitile memory to be easily recalled and displayed at any time.
1.1 Display Options Available
The VK204-25 is complimented with a wide selection of filters including blue, green, grey and red. If the
VFD will be in direct sunlight, the grey filter will prevent the displayed text from ’washing out’. Extended
voltage, and temperature options are also available, to allow you to select the display which will best fit your
project needs.
