Microcontrollers on boards using the NB3N551
NB3N551: common questions
Where can I find a NB3N551 reference design?
Each of the 3 boards on this page is a real design using the NB3N551. 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 NB3N551 use?
Most are built on FPGA (2).
How big is a typical board using the NB3N551?
The median is 118.6 × 83.2 mm, and 33% are two-layer designs.
What is the most popular open source board using the NB3N551?
By GitHub stars, Fmcw by matthuszagh, with 66 stars.
Can I simulate one of these boards using the NB3N551 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.
