4 open source boards using the MSGEQ7
Real designs built with the MSGEQ7, from public GitHub projects: a quick way to see how others power, decouple and connect it. Each board comes with its KiCad files, full parts list and a render — and you can simulate its firmware on HardLabs.

MSGEQ7: common questions
Where can I find a MSGEQ7 reference design?
Each of the 4 boards on this page is a real design using the MSGEQ7. Open one to see how it is wired up, with the full BOM, a render of the layout and links to its KiCad files.
Which microcontrollers do boards using the MSGEQ7 use?
Most are built on ESP32 (2) and AVR/Arduino (1).
How big is a typical board using the MSGEQ7?
The median is 86.4 × 72.3 mm, and 100% are two-layer designs.
What is the most popular open source board using the MSGEQ7?
By GitHub stars, In13-Spectrum-Analyser by ImNoahDev, with 3 stars.
Can I simulate one of these boards using the MSGEQ7 before building it?
Yes. HardLabs turns a board's netlist and BOM into a working simulation, so you can boot and test firmware against it with no hardware on your desk.
