Microcontrollers on boards using the W5100
What boards using the W5100 are built for
W5100: common questions
Where can I find a W5100 reference design?
Each of the 4 boards on this page is a real design using the W5100. 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 W5100 use?
Most are built on AVR/Arduino (2) and PIC (2).
How big is a typical board using the W5100?
The median is 157.8 × 111.7 mm, and 33% are two-layer designs.
What is the most popular open source board using the W5100?
By GitHub stars, .C68 by ProbablyNotArtyom, with 51 stars.
Can I simulate one of these boards using the W5100 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.
