PCB to hold (4) IV-6 Vacuum Florescent Displays (VFD) and their associated driver ICs (UDN2981A / MIC2981). All segments are paralleled (including the DP) for multiplexing via control of the 4 separate VFD grids. Decimal points can be multiplexed, or fixed at a single location via solder-jumpers. Board requires +5V switch logic, +1V and +35V for the VFD filaments, grids, and segments. Three on-board switches (to GND) allow further customization.
