What boards using the SI5351C are built for
SI5351C: common questions
Where can I find a SI5351C reference design?
Each of the 3 boards on this page is a real design using the SI5351C. 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 SI5351C use?
Most are built on NXP (2).
How big is a typical board using the SI5351C?
The median is 120 × 75 mm.
What is the most popular open source board using the SI5351C?
By GitHub stars, Marzipan by Charmve, with 352 stars.
Can I simulate one of these boards using the SI5351C 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.
