Description

OPIC Microphone (MP PCB)

Based on Roger Shores OPIC.Multi Pattern Microphone Circuit - a PCB fitting in some microphone bodies.

You also need this additional PCB, it provides the necessary polarisation voltage:

OPIC Microphone (LDC) - Share Project - PCBWay

Rogers project:

OPIC Multi Pattern (jp137.com)

Keep in mind that I changed some part descriptions, so refer to the BOM on this page. I also added the possibility to use a pad switch.

You can use headers as a pattern and pad switch, but if you want to use real switches, this may help:

Pattern and Pad Switch Holder for BM700/BM800 by MicScharf - Thingiverse

If you want the high impedance parts not on the PCB use torrets and bend pin 3 and 5 of the OPA 1642 up.
