What boards using the OPA340NA are built for

OPA340NA: common questions

Where can I find a OPA340NA reference design?

Each of the 3 boards on this page is a real design using the OPA340NA. 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 OPA340NA use?

Most are built on STM32 (2) and PIC (1).

How big is a typical board using the OPA340NA?

The median is 50 × 30 mm, and 100% are two-layer designs.

What is the most popular open source board using the OPA340NA?

By GitHub stars, OtterIron Devkit by Jana-Marie, with 316 stars.

Can I simulate one of these boards using the OPA340NA 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.
