This board is for a single channel microphone preamplifier. Unlike most ESP boards, this one is double-sided with plated-through holes. Be careful during assembly, because rework will almost certainly damage the PCB unless you have experience with double-sided boards.

The layout (marked as MIC001) contains one mono preamplifier, and is identical to the description in the project article. Use a P05 power supply or similar - a single supply will power several preamps, or a preamp and various other boards.
