VK204-25
The VK204-25 is a 20x4 intelligent VFD display (Vacuum Fluorescent Display). Engineered to quickly and easily add a powerful HMI to any application. VFD Displays offer exception performance in extreme temperatures, keeping their quick response times, high (170 degree) viewing angle and long life.
Multiple communication protocols such as Serial RS232, TTL, I2C, and USB communication modes allow the VK204-25 VFD to be connected to a wide variety of host controllers.
Our Intelligent Character VFD displays provides you with a cost-effective industrial HMI user interface solution for that great product/project you are developing. These VFD displays features optional on-board large and medium digits, bar graphs all with the convenience of a 25 key matrix keypad will allow fast development for any application.
