LM3915 DIY VU
Meter Kit Parts, v4.0:
This is a revised and improved version of the LM3915 Audio Level
Indicator (VU Meter). The Circuit and PCB are custom designed and
tested to offer a better quality and response in comparison to other
kits that maybe for sale anywhere else. The PCB v4.0 is a
smaller-size revision as compared to v3.0 and the circuit components on
v4.0 have been revised to provide a higher audio signal sensitivity and
response. As a DIY Kit, it will require assembly and soldering;
however, we have designed the PCB for easy component placement and
soldering.
The improved and revised smaller-size PCB v4.0 includes the following
features:
- Custom
Made PCB Design with smaller-size (v4.0).
