Graphic Equalizer Display Filter Breakout - MSGEQ7

Audio equalizer for use with graphic displays. This simple board breaks out the MSEQ7 according to the application notes, but is not Arduino specific. Currently this is for through hole parts for ease of soldering, look for the SMD version soon.

Pinout:

  • LT - Left analog input, use STR and RST to get each band (0-6) of the audio spectrum
  • RT - Right analog input, use STR and RST to get each band (0-6) of the audio spectrum
  • STR - Strobe digital output, controls the strobe of the equalizer IC
  • RST - Reset digital output, controls the reset of the equalizer IC

Bill Of Materials:

  • 33pF PTH Ceramic Capacitor x2
  • 0.1uF PTH Ceramic Capacitor x4
  • 1000pF PTH Ceramic Capacitor x2
  • 200kOhm PTH Resistor x2
  • Stereo Audio Jack 3.5mm x1
  • MSEQ7 IC x2
