Microcontrollers on boards using the 4N35
What boards using the 4N35 are built for
4N35: common questions
Where can I find a 4N35 reference design?
Each of the 11 boards on this page is a real design using the 4N35. 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 4N35 use?
Most are built on NXP (5) and AVR/Arduino (1).
How big is a typical board using the 4N35?
The median is 85.8 × 61 mm, and 100% are two-layer designs.
What is the most popular open source board using the 4N35?
By GitHub stars, Precharge by LSUTigerRacing, with 7 stars.
Can I simulate one of these boards using the 4N35 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.
