EasyVFDD: Make your own VFD Matrix display

What is it?

This is a retro display driver designed to control multiple IV-26 VFD tubes.

What makes it special?

• On-board 5V to 28V step-up converter

• Works with 3.3V logic

• Each board drives up to three IV-26 VFD tubes

• Allows daisy-chaining of multiple units

• Silent operation with no noise

• EasyNixie-compatible pinout

• RGB lighting support

• Arduino Library available

What is it good for?

Three tubes are actually enough to display numbers and letters, allowing you to create clocks or scrolling text. An alphabet example is available in the library repository.

How do I connect it?

Connect it the same way you would connect a shift register.

• STCP->GPIO

• SHCP->GPIO

• DSIN->GPIO

• DSOUT->DSIN of the next EasyPDLC in daisy chain or 'not connected'

• OUT_EN->GPIO

• VLOGIC->3.3V or 5V depending you your MCU logic votlage

• VPOWER->5V

• GND->GND

Warning

Make sure you are using IV-26 type 1! Type 2 and type 3 used in Elektronika clocks have some pixels connected together!
