OPIC42 LDC Circuit for TLM 102 sized body

Round OPA1461 based LDC mic circuit for a TLM 102 sized body

Published so that anyone can access the circuit design easily, this circuit is about 38mm in diameter, so it's small enough to fit in a very large number of mic bodies both large and small, so this PCB is NOT limited to a TLM-102 style body despite being built for that.

Based on THIS project by Rogs (specifically the OPIC.42 variant), all credit for the original schematics to him.
