4 open source boards using the OPA140
Real designs built with the OPA140, 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.

Microcontrollers on boards using the OPA140
What boards using the OPA140 are built for
OPA140: common questions
Where can I find a OPA140 reference design?
Each of the 4 boards on this page is a real design using the OPA140. 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 OPA140 use?
Most are built on AVR/Arduino (1).
How big is a typical board using the OPA140?
The median is 87.8 × 50 mm, and 25% are two-layer designs.
What is the most popular open source board using the OPA140?
By GitHub stars, Smu main 1 by jaromir-sukuba, with 188 stars.
Can I simulate one of these boards using the OPA140 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.
