Has anybody ever tried to connect the Wiznet W5100 ethershield (NOT the MEGA compatible version) to an Arduino Mini ?

I would like to make both work together for a reduce space project.

Any help would be greatly appreciated

Since the W5100 uses SPI you should be able to hook up the four SPI pins, power and ground and be good to go.

You mean to connect pins 10 - 13 of the ethershield to pins 10-13 of the mini ?

The ethershield does not have the SPI connector, it's the old version (not MEGA compatible).

I'll need to make 3.3 V power supply too as the mini does not have it, looks like the ethershield really needs the 3.3 V

Yes, pins 10-13 for SPI (unless Slave Select uses a pin other than 10), Ground, and Power.  Check your shield.  It might already have a 3.3v regulator connected to +5v.  At least one of the older Ethernet shield designs has the regulator on-board.

Since the Ethernet shield is almost as large as a traditional Arduino do you really save much space with a Mini?

I'll gain a lot in height, but not in surface, that's correct.
I have 2 mini's that i've never used, now I'm doing a home automation project and I'm trying to use the mini's for this project.

Hey all. Just yesterday I posted this as well. I connected all the pins from the mini to the Ethernet shield and still no go. I'm running the pro mini off of USB power. should i hook it up to a 3.3v. Thanks

What shield are you using ?
