The enc28j60 MAC address is randomised at bootup, because just like the LAN9514 chip used on Pis with built-in Ethernet, the MAC address needs to be programmed from an external EEPROM (see ). I don’t have an ENC28J60 myself, but I did a bit of digging…

(Update to add) Sources close to RPi have told me unofficially that it will probably be fine to run this ethernet board on the 3V3 rail of the Pi Zero. It might therefore be better practice to run it from a separate supply. Now I’ve looked at the datasheet for the chip, I’m surprised it works at all.Īccording to that, page 80 states a power usage of 160 mA which is a lot more than the nominal 60 mA 3V3 rail limit on the Pi. But for an Internet of Things (IoT) device or for most purposes it’ll be enough. So it isn’t going to win any speed awards, and probably isn’t good enough for streaming HD video.

What does that mean in real money? On my LAN, it took 3m 45s minutes to download an 85 MB file from Pi to Macbook Pro and 3m 18s to upload it to the Pi Zero. Pi2 with ethernet onboard 74 Mbaud down, 5.86 MBaud up Then run it with speedtest-cli Speed Test Results

You can use a command line version of if you install it... The ethernet chip is specified at 20 MHz maximum, so best avoid going above that. If you want to tweak the SPI clock speed or INT port you can use dtoverlay=enc28j60,int_pin=25,speed=12000000 and tweak those variables. Then when you reboot, your ethernet port should ‘just work’. If you changed anything, you’ll need to reboot for it to take effect.Īdd the following to your /boot/config.txt Menu > Preferences > Raspberry Pi Configuration So I tweeted this terrible photo with two puns embedded at no extra charge… I instantly soldered a header to my Zero and tried it on that. It was almost boringly easy and took about half an hour. An ifconfig showed me I had an ethernet connection. I wired it up carefully, booted the Pi, tweaked a config.txt line, enabled SPI and rebooted.Īnd that was it. As I had not yet soldered a header to my Zero, I decided to try it on an A+ to start with to see if I could get it working. I rummaged in my box of “Things I’ll get around to using one day – perhaps” and found the ethernet board surprisingly quickly. I said something nice about device-tree – had to happen one day.) It Took Me About Half An Hour The procedure has been much simplified thanks to device-tree.

Fortunately, in the meantime, a device-tree driver has been produced for this chip, which means there is no need to compile anything, mess about with the kernel or even do very much at all. Provoked by the mass of “I want an ethernet port on my Zero” comments, I decided it was time to have a go. So it sat on my desk for a while and eventually went in my box of “Things I’ll get around to using one day – perhaps”. It looked hard and a bit scary (nobody had RasPi.TVed the procedure) and I had other stuff to do. When it arrived I did a classic geek thing. It has an ENC28J60 chip on it, an ethernet port, a 25 MHz crystal and some resistors and capacitors… There was a forum thread about it, where people had done this, so I bought a little ethernet board for Arduino. Then someone (I think it was Alex Bradbury) pointed out that you can add ethernet over SPI.
#Logic power qts1081b serial
With no USB or ethernet, the only way I could log into it was through the serial port. Some time ago I managed to kill the ethernet/usb hub chip on one of my model B Pis. The other option, that we’re going to cover today, is to add an external ethernet port using the SPI pins on the Pi. B+ is fairly inexpensive these days, but also the Pi2 B has ethernet. Well the obvious solution would be to buy a B model Pi. The two most obvious ones are cost and board size (it would have almost doubled the size of the Zero) So What’s To Be Done If You Need Ethernet? There are reasons why ethernet was not included. One of the most common “I wish it had”s was an ethernet port. Whenever a new product is released, people air their opinions in the forums on what they would have liked it to have.
The Pi Zero attracted a huge amount of attention, which is great for the educational mission of the Raspberry Pi Foundation.
