This module is designed for VFD tube IV-22 (ИВ-22), made in former Soviet Union around 1990s. Combined with classic VFD tube, gold-plated tube basement, gold‐plated PCB, RGB background LED, IV-22 module can be applied in varies of applications, presenting colorful effects. It is an all‐in ‐one design. Boosted circuit, logic controllers, and plug sockets are all integrated. Several modules can be plugged in serial for customized needs. This makes the controlling much easier, especially for Arduino, and other similar open‐source MCU platforms. Users can focus on the presentation and application, no need to worry about the voltage management or connections.
