5V Ready-VFD Matrix Module for Arduino/STM32 etc.

Caution:

1.High Voltage(~100V) on board,do not touche any part of PCB with power on;

2.May have tiny sound when displaying that is from filament which is caused by internal driving IC inside PANEL in scanning freq; You can install the module inside an enclosure to reduce the sound;

Features:

1).5V Ready, easy to be used. Can connect to your ARDUINO UNO board with only 3 signal wires;

2).High efficiency power circuit, High Brightness;

3).All SMT components, very thin PCB, easy to be driven;

4).Logic part support 5V or 3v3 signal;

5).Contains over-current protection, and reverse connection protection circuits;

6).Open source ARDUINO NUO source code, pure C code, easy to be used, also provide a simple flip clock source code for ARDUINO UNO.

7).Simple 3-wire SPI interface, with EN pin, support shutdown the High Voltage and Filament Supply completely.

Interface:

3-wire SPI: DIN/CLK/LATCH(CS)

---------------------------

+5V (main power.)

GND

DIN

CLK

LATCH(mark:CS on PCB)

-------Other pins----------

+3V3 out 100mA (max)  (optional)

INT-SYNC out (optional)

EN High voltage & filament supply enable(optional)

Logic part is 5V and 3v3 compatible.
