Description
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.
