VFD2515 Sound-Activated Music Spectrum — 5-12V Vacuum Fluorescent
The original GEEKTONE VFD2515 sound-activated music spectrum display. It uses a VFD2515 vacuum fluorescent display to render a 17-band spectrum and VU animation in real time. The board runs from 5-12V and accepts either line-level audio or built-in microphone input. Two push buttons cycle through display modes and adjust sensitivity. This is the board most often shown in GEEKTONE's demo videos.
