NEW PRODUCT – 128×64 Graphic VFD (Vacuum Fluorescent Display) – SPI interface

Window-143

NEW PRODUCT – 128×64 Graphic VFD (Vacuum Fluorescent Display) – SPI interface. For blue-glow lovers, this is a graphical VFD with 128×64 bit resolution and a stunning high-brightness/high-contrast look. This module would be a great addition to any project where readability is a must – you can read it in daylight, and at any angle.

Window-1-79

The VFD module supports both 8-bit parallel and SPI modes of communication. The SPI protocol allows to write and read pixels so no RAM is required to buffer the display (most 128×64 SPI displays require a full 1K RAM buffer since you cannot read from the display memory). The module requires 5V, and does draw quite a bit of current, up to 500mA. There is a VFD driver and 60V boost circuit on the back. You can probably use 3.3V logic to communicate with the module, as long as it is powered with 5V

Of course, we wouldn’t leave you with a datasheet and a “good luck”: We have a detailed tutorial and example code in the form of an Arduino library for text, bitmaps and graphics.

You can download our VFD graphic display Arduino library from github which comes with example code. The library can print text, bitmaps, pixels, rectangles, circles and lines. The code is simple to adapt to any other microcontroller.

In stock and glowing now.

  1. Is that just the camera, or does it look like those filaments are a little bit too hot in the top picture? I think they’re not supposed to be hot enough to light up. Right?

    Nice product by the way!

  2. jac- just the camera/photo!

  3. what is the refresh speed like? If it’s pretty good I’d love to use this in a motorcycle speed/tachometer project I have in mind.

    Could we get a video of it’s operation?

  4. @fireaisr – we’ll post up a video soon and/or show it off on the this week’s ask an engineer!
