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 and 5V 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
• Schematics available from the Datasheet tab

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! Types 2 and 3, used in Elektronika 7 clocks, have some pixels connected together!

Warning

This board is too large to fit into the DUO Nixie shield, so they are not compatible.
