Microcontrollers on boards using the ADuM121N

ADuM121N: common questions

Where can I find a ADuM121N reference design?

Each of the 2 boards on this page is a real design using the ADuM121N. 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 ADuM121N use?

Most are built on RP2040/RP2350 (1).

How big is a typical board using the ADuM121N?

The median is 76 × 58 mm, and 50% are two-layer designs.

What is the most popular open source board using the ADuM121N?

By GitHub stars, NMEA0183Adapter-7.1 by peterantypas, with 444 stars.

Can I simulate one of these boards using the ADuM121N 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.
