About the Piezo-9v PCB

Piezo-9v is an open source PCB design by Supermagnum, published on GitHub under the CC0-1.0 license. It is a 2-layer board measuring 70 × 54.5 mm, with 26 components from 23 distinct parts.

Other key parts include the LM386N-4/NOPB and NE5534. By type, the board carries 11 capacitors, 7 resistors, 3 diodes, 2 ICs, 1 battery holder and 1 switch.

It belongs with the audio designs in this gallery.

From the project

A small PCB for pizoelectric amplifier, runs on 9V

It's fairly easy and straight forward to solder the components to the circuit board, a nice pointy soldering iron, solder,and a ohm or multimeter is all that is needed.

Please use 0,5 W metal film resistors with 1% tolerance or better and audio quality capacitors. C0G (NP0) or X7R capacitors is very good.

Of course one needs a suitable metal box, and the circuit boards components must not come in contact with the metal box. That will cause short circuit, so it's best mounted on conducting stand offs because the corner pads on the PCB board must be connected to the metal box. Check that no…
