I really like this 12-bit VFD fluorescent digital tube clock, it’s mini and cute. That is, the leftmost digit can only display -, and the third digit from the bottom can only display the upper half.
The pipe is fixed by welding with 0.8mm brass wire.
There are two short contacts at the bottom. The D1-D2 short circuit pulls the HV5812 chip BLANK low to light up the VFD. The PWM signal can also be input through the module pin to control the VFD brightness. The default short circuit is short circuit. D3-D4 is short-circuited to enable the VFD drive circuit and is disconnected by default.
The microcontroller driver module is in the next project.
