Specifications

This is an MSGEQ7 spectrum analyzer breakout board. It divides the incoming audio spectrum into seven bands. These seven frequencies are peak detected and multiplexed to the output to provide a DC representation of each band. The operating voltage is 2.7V to 5.0V.

The MSGEQ7 can be used to analyze audio fed in through the stereo jack on the board. The data can be sent to an Arduino, Raspberry Pi, BeagleBone, or other microcontroller. This can be useful for timing lights to music.


The mono version has the left and right channels fed into the onboard MSGEQ7 integrated circuit. This gives a good representation of what is heard by your ears. The stereo version analyzes both channels separately using two onboard integrated circuits. The board measures 1.3" by 1.0" (33mm by 27mm).

MSGEQ7 Stereo - Outstanding

I just purchased 5 more of the MSGEQ7 stereo board. These are great. Very clean and well laid out in a pretty small package. We use them to control LED modules and servos for our Halloween display and the sample code was relatively easy to modify for our needs Great service, fast shipping and the boards are rock solid.
