1).5V Ready, easy to be used. Can connect to your ARDUINO UNO board with only 3 singal wires;
2).High efficiency power circuit, no transformer, no heat, Low HV, very safe, High Brightness;
3).All SMT components, very thin PCB, easy to be drivered;
4).All segments in the VFD pannel can be lighted up, including the dots,colons;
5).Contains over-current protection, and reverse connection protection circuits;
6).Open source ARDUINO NUO source code, pure C code, provide high level vfd_printf() function, easy to be used, also provide a simples clock source code which you can adjust the Hour and Minute for ARDUINO UNO.
7).Simple 3-wire SPI interface, with EN pin, support adjusting the global brightness and shutdown the High Voltage and Filament Supply completely.

Interface: 3-wire SPI:

EN - High voltage & filament supply enable(optional)
