When searching for VU meter circuits, many use the LM3916 LED bar graph driver, which already has the right scaling built in. When searching for VU meter circuits, many use the LM3916 LED bar graph driver, which already has the right scaling built in.
But this chip is obsolete and not produced any more, so we designed our own chain of comperators to drive a set of LEDs. But this chip is obsolete and not produced any more, so we designed our own chain of comparators to drive a set of LEDs.

## BoM ## BoM
Approximate prices in Euro. All prices without VAT and for one piece unless otherwise noted, even if the BOM already asks for more.
So it's expected to get lower when ordering a full set for multiple units.
Connectors and Buttons (User Interface) #### Line I/O Board Components
BOM for one PCB, needed 1x for whole assembly.
Electrolytic capacitors should have 25 V voltage rating, unless otherwise specified.
