As added to the schematics as errata text, there are a few bugs in the PCB design, which need to be fixed in the next revision:

  • The Potentiometer_Alps_RK09K_Single_Vertical footprint in the KiCAD standard library is wrong. Pins 1 and 3 need to be swapped.
  • Remove the power interconnect on the mouse bites, connect the ground plane at the top PCB all the way.
  • Remove the high pass filter between microphone pre-amp and gain stage. Any capacitor (electrolytic, NP0 ceramic of PP foil) has quite a negative impact on the sound quality.
  • Remove the VU meter signal smoothing/ low pass filter.
  • Use +15V for V_LED directly.
