ENC28J60 Ethernet Controller

A Robust Controller Found On Many Boards To Permanently Wire Your Device To A Network

This is a popular Ethernet controller that is used on a number of breakout boards.


The boards use the SPI interface.

Operating Voltage

The operating voltage is 3.3V.

To operate this breakout board with a 5V microcontroller like Arduino, most microcontroller boards have a dedicated 3.3V pin that can be used. A separate level shifter would be required to translate the SPI connections.

MAC address and IP configuration is done in software. A suitable library can be found here. There are many more libraries for the ENC28J60 chip.

Data Sheets


Please do leave comments below. I am using utteran.ce, an open-source and ad-free light-weight commenting system.

Here is how your comments are stored

Whenever you leave a comment, a new github issue is created on your behalf.

  • All comments become trackable issues in the Github Issues section, and I (and you) can follow up on them.

  • There is no third-party provider, no disrupting ads, and everything remains transparent inside github.

Github Users Yes, Spammers No

To keep spammers out and comments attributable, all you do is log in using your (free) github account and grant utteranc.es the permission to submit issues on your behalf.

If you don’t have a github account yet, go get yourself one - it’s free and simple.

If for any reason you do not feel comfortable with letting the commenting system submit issues for you, then visit Github Issues directly, i.e. by clicking the red button Submit Issue at the bottom of each page, and submit your issue manually. You control everything.


For chit-chat and quick questions, feel free to visit and participate in Discussions. They work much like classic forums or bulletin boards. Just keep in mind: your valued input isn’t equally well trackable there.
