128x64 Graphic VFD (Vacuum Fluorescent Display) - SPI interface
A 128×64 pixel graphic Vacuum Fluorescent Display (VFD) with a distinctive blue-green glow and exceptional readability. VFDs offer high brightness and contrast that remains legible in direct sunlight and at wide viewing angles — ideal for projects where display clarity is critical.
The module supports both 8-bit parallel and SPI communication. In SPI mode, you can read and write pixels directly, eliminating the need for a 1K RAM frame buffer that most SPI-connected 128×64 displays require. The module runs on 5V and draws up to 500mA, with a built-in VFD driver and 60V boost circuit on the back. The SPI data lines are likely 3.3V-tolerant when the module is powered at 5V.
