This Vu-Meter is composed of four LM3915 in cascade, for a total of 40 LEDs and a range of 90dB. The circuit must be powered with 9V DC and connected to the amplifier output (or preamplifier).
After trying the excellent service offered by JLCPCB I recommend it, the quality of the PCB is high, customer service is always available and professional, the time of realization is short and the delivery of PCBs is by express courier. JLCPCB is a great place to get hight quality custom circuit boards at an extremely low price, you can buy 5 PCB Boards (Any Color) for 2$ !!!
