4 open source boards using the OpAmp
Real designs built with the OpAmp, 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.

What boards using the OpAmp are built for
OpAmp: common questions
Where can I find a OpAmp reference design?
Each of the 4 boards on this page is a real design using the OpAmp. Open one to see how it is wired up, with the full BOM, a render of the layout and links to its KiCad files.
How big is a typical board using the OpAmp?
The median is 160 × 100 mm, and 100% are two-layer designs.
What is the most popular open source board using the OpAmp?
By GitHub stars, VCO by Desval27, with 0 stars.
Can I simulate one of these boards using the OpAmp 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.
