• Here we have another version of VU meter based on original design from s-o.webnode.cz . In this configuration we used some SMD components to make the PCB small and possibly more versatile, the LED had been removed from the board and replaced with a string of ws2812 RGB 16 per channel on a pluggable boards.
  
  There are 2 versions of the control boards, one with DIP package for the MCU and one with SMD version of the Microcontroller.
  Also there are 2 display boards one os 5 inches long and other is 4.3. However they can be replaced with regular ws2812 strings.
