2 open source boards using the RJ45

Real designs built with the RJ45, from public GitHub projects: a quick way to see how others power, decouple and connect it. Each board comes with its KiCad files, full parts list and a render — and you can simulate its firmware on HardLabs.

RJ45: common questions

Where can I find a RJ45 reference design?

Each of the 2 boards on this page is a real design using the RJ45. 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 RJ45 use?

Most are built on FPGA (2).

How big is a typical board using the RJ45?

The median is 85 × 85 mm, and 0% are two-layer designs.

What is the most popular open source board using the RJ45?

By GitHub stars, Nl2sch by tpecar, with 19 stars.

Can I simulate one of these boards using the RJ45 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.
