VFD Tube (Arduino Compatible)
The VFD Tube Module brings a classic vacuum fluorescent display (VFD) to modern microcontroller projects. Built around the Soviet-era IV-22 tube, this self-contained module integrates the high-voltage boost circuit, 74HC595 shift-register driver, and an RGB background LED — so you can focus on code and design rather than complex wiring.
Modules connect in series using just four I/O pins from an Arduino or other MCU platform, making it straightforward to build multi-digit clocks, counters, and decorative displays with the distinctive cyan VFD glow and customisable RGB backlighting.
