I wanted to see if anybody got this working with the W5500 also, even though it says it is not tested, it still says it should be supported.

Well, I installed the proper firmware and followed the examples for the network module. Mine is hooked up as
nic = network.WIZNET5K(pyb.SPI(1), pyb.Pin.board.X5, pyb.Pin.board.X4)

My PyBoard reads several sensors and uses a simple http GET to post data to my server, 10 times per hour. It has been doing that non-stop since mid May and hasn't missed a beat. I intend to implement a watchdog timer but so far the board hasn't failed. So for my (hobby) purpose, it is quite stable enough.

Not sure what you mean by dependability.
hi HansvL, tried the same but get no connection with WIZ820io.

nic.ifconfig() reports False
nic.ifconfig() reportrs (, 255.....)
tried it with latest firmware for pyboard V1.1 .
tested with external 3.3V.
Is there anything else to take care with cabling. connected as described

MOSI connected to X8
MISO connected to X7
SCLK connected to X6
nSS connected to X5
nRESET connected to X4

I need the board for mqtt publishing accel values and uart communication with two sensors. Wifi is no option.
Working on network connection since one day without success!
Would appriciate help or even donate for working code, maybe will set up a project in freelnacer.

Sorry, I didn't touch this project for the last 3 years and I am not in a position to assist you with a live system.
Some (probably obvious) remarks from memory:
-I used the precompiled "network" version of Micropython. V1.8.7 iirc.
-Your cabling is OK. Also GND and 3V3. I used the 3V3 output from the PYB.
-I have a 3 second delay after power-up before addressing the adapter. I think I got this from its specsheet.
-No DHCP (that I could find) so configure using nic.ifconfig(('', '', '', '')) to fit your network.

Hello all, I have wired a WIZNET5K board (ethernet cable not wifi) to a pyboard and it works but with a static IP, I need to use it by DHCP in my company buy I can not find any way to configure it, probably it is not supported do you know if it is possible to set DHCP somehow?.

Thank you very much
