IV-3 VFD shield for Arduino

1 Overview

This Arduino shield is capable of driving 4
Russian IV-3 7 segment VFD tubes.
3mm LEDs provide background lighting for
the tubes.
The design is completely based on through
hole components, no SMD components
were used. As such, the PCB can easily be
assembled
by
anyone
soldering experience.
Also, the components used are cheap and
easily available.
As
this
was
designed
educational, easy to build project it is not
the best possible solution to drive these VFD tubes from a technical point of view.
Instead of the BC547 and BC557 transistors we could have used A2982W source drivers,
or we could have replaced the transistors by a Supertex high voltage source driver IC
with internal shift register. Unfortunately these may be hard to get and come very often
in SMD packages.
