Your cart is empty. 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).

I have been looking for a quick way to make a light organ when I came upon a recomendation for this chip. When I found it on the board and ready to go, I grabbed one and got to work. I have great memories of an old buddy of mine in the US Army back in the early 1970's who, like me was a communicator. He had used his skills in electronics to build a light organ to get a bit more out of the wonderful music that was popular back then. His was not done very well but did appear to go alone with the beat of the music. Over the years I have dallied with different methods, even purchased a kit from Radio Shack that worked but not well and fell apart after a few weeks. This little gadget works great. It is so simple to set up with an Arduino to make a light organ that does the trick with very little work. I have plans to expand my initial trial with the chip using a few LED's. My plans involve using some MOSFETS to power some large LED'S to make a system about the size of a modern stereo speaker to sit atop my entertainment system. I know I will never get one that will match my great memory of my buddies in his trailer house on the outskirts of El Paso back in the early 70's because, well memories have a way of amplifying when they are great but I bet I will have one that produces better in sync music then his ever did.

I bought the mono version and it seems to be working well.
