Hi Guys. I want to use my Nano33 in a location where the wifi is unreliable but I can run an ethernet cable. I have purchased a Wavelength ENC28J60 card (from the PiHut so hopefully good quality) and wired it thus:
I have tried about twenty different programmes/libraries, but none of them seem to bind the ENC28J60 to the Nano33 and the card never appears on the network.
Any recommendations or advice on how to get this working would be appreciated.
You ll need an ethernet shield for this one
Is this the one that I need to modify to use with the Nano33?
use my EthernetENC library with the enc28j60 module. the library is in Library Manager. see the examples of the Ethernet library.
the Nano shields are for a 5 V Nano and require a modification to work with a 3.3 V Nano.
pin 13 should go to SCK. pin 10 is CS not INT. you have reset wired to CS on the picture
https://github.com/jandrassy/EthernetENC/wiki/SPI-Wiring
ya to get it connect with ethernet cable in a compact way this type of modules are best option . . .
Or this type model you can go with
use the 2x3 SPI header on Uno WiFi.
pins 11 to 13 are not SPI on Uno WiFi Rev 2.
Ya exactly i agree
a bit changes we need tp make here with a check on programing part too may be . .
Thanks. Are you saying 10 to CS and on the 2*3:
1(copi) ->MOSI
4(cipo) -->MISO
3 -> CLK
yes. and fix the enc module end connections too. at least on the picture you have some of them wrong as I wrote in my first comment.
@King_RAJ_Enters please stop. you are not helping
Strange ! I supported your idea @ #8 and you are behaving like this ???
Is it some kind of competition or debate we are doing here hmm ???????
We are learners and about to discuss & share knowledge here with each other
You are not supposed here to judge people helping or disturbing or arguing
and who said i am not helping ??? check the links i have forwarded . . .
Ok , You you hold very very good knowledge i appreciate that but may be . . . may be his experiment is going through some other kind of issue
So he may solve it with the clips . . it may be possible na ??
So in that sense i hv forwarded . . . .
The pin-out info I have for the Uno Wifi Rev2 does show SPI on pins 11 to 13 but I have rewired as suggested. Sorry the photo is a bit messy.
However I think I am still stalling at Ethernet.begin(mac, myIP);
sorry yes, there is SPI on 11 to 13.
wire MISO to MISO, MOSI to MOSI. it is Master In/Out Slave Out/In.
I think this is the problem I have had all along the Ethernet.begin doesn't bind the enc28j60 to the arduino
add Ethernet.init(10);
the WebClient example of the Ethernet library is the best test sketch
Thanks. I've tried the WebClient test sketch (again).
With #include <Ethernet.h> I get what I'd expect which is:
FWIW my switch can see the ENC and is tx to it but gets no rx
The whole sketch is here below:

did you correct the wiring?
