What boards using the M3406 are built for
M3406: common questions
Where can I find a M3406 reference design?
Each of the 3 boards on this page is a real design using the M3406. 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 M3406 use?
Most are built on ESP32 (1), Nordic nRF (1) and RP2040/RP2350 (1).
How big is a typical board using the M3406?
The median is 34.8 × 34.8 mm, and 33% are two-layer designs.
What is the most popular open source board using the M3406?
By GitHub stars, Kerberos by FrankBuss, with 82 stars.
Can I simulate one of these boards using the M3406 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.
