Jumpers
The VU Meter Kit can be installed either horizontally or vertically. Normally, VU Meter movement go from LEFT
RIGHT or BOTTOM
TOP direction.
That means, when the VU Meter Kit board is installed in a vertical configuration, you want your LED movement
going from BOTTOM
TOP.
If the VU Meter Kit board is installed in a horizontal configuration, you want your LED movement going from
LEFT
RIGHT.
Four (4) on-board jumpers are provided on the PCB to allow you to change the direction of LED movement
display. Just move ALL jumpers either to the HORZ or VERT position (for Horizontal or Vertical position
respectively).
IC Chip
The IC chip used in the VU Meter Kit is a 9-lead SIP (Single Inline Package). One side of the chip will have a V
notch. This designates where pin #1 is located. Install the IC Chip with pin #1 (V notch) on the left side of the
board (looking at the VU Meter PCB from the front view.)
