You receive BARE PCB no components, one board is for 6 VFD tubes ..!!!!! PICTURE IS FOR REFERENCE ONLY !!! Tested only with IV6-tubes NOTE!!!!: more IV-3 versions with different pinout !!! IV-3 Confu…

NOTE!!!!: more IV-3 versions with different pinout !!!

IV-3 Confusion ...

AXIRIS IV-6 Shield for Arduino is super great project, specially power supply is very good designed. etc. filament is driven with AC voltage which is recommended for VFD. 12V input voltage is 3x multiplied to make about 32V I am redesigned board for easier soldering, all components are in lines with same value

added buttons for HOUR / MINUTES
speaker driver for make alarm clock, in current firmware is only hour beep implemented
components values on PCB
DS3231 with battery backup CR1220
Enhanced to 6 DIGIT
hand painted curved traces for more retro look
all outputs are marked on pcb for better debugging
schematic is almost unchanged, some pins are swapped for better PCB routing

I created simple CLOCK arduino sketch (firmware)
