Review on π Enhanced Kemo M040N Preamplifier Module by Shelly Daniel
Common land is a problem.
So this preamp works, but I couldn't use it because of the common ground wire between the positive voltage and the mic input. The output of this was supposed to go to the input of the signal processor, but I couldn't connect both to the same power supply because the preamp was tuned to the local radio station.
