Connect One Ethernet shield

I have a iL-SM2144N1-I with headers.

Something looks wrong on your board or maybe I have the wrong part or.... is the top view the bottom of the top view?

I have a iL-SM2144N1-I with headers.

I think Mouser has the PNs confused. I have this one and I think you have this one. The only difference is one has headers and one does not and the one with headers does not have the teensy-weensy humanoid-unfriendly connector shown in Fig. 3-1-1 of the datasheet (p4-1) for ours.

I've been working off the drawings in the datasheets so I think things are OK but I have been jumping back and forth between the two shields as well as two other projects. I'll print out a life-size copy of the .PNG and see if things fit. What, specifically, looks wrong? It mounts in the 10 leftmost holes of the two 15-pin sockets (the nano Socket iWiFi uses all 30 & the iWiFi uses the 2x6x100 socket) with the RJ45 to the left. (Spark Fun has 10-pin and 5-pin 2mm sockets which I hope will work end-to-end for the 30-pinner. They will mail small shipments, saving cost.)

I now have the Edit function back but with a 10-minute limit which is too short for slow, dim-witted geezers. At least I no longer am pestered by the random phrases - any semi-intelligent bot would quickly figure out there were only 5-6 answers, anyway.

The actual connections for our modules are shown in this post. That is part of another, much larger project. The other project taking up most of my time is shown here.

The ones I have been using have the 30 pin molex on the bottom and have been coming with the two ten pin headers on the sides installed. I also purchased 2mm headers that I have not used yet. Maybe the next batch will need them...

The thing that looks wrong, and it is probably the way I am looking at the drawing. When looking down my module with the RJ45 to the right, the serial pins are on the upper header, J7. To me it looks like your drawings show a view from the bottom of both layers. Putting the RJ45 over the EEPROM...

That's possible - I was using the pinouts from the data sheets and they may be top views when I was thinking the opposite (or vice versa). Try it with the RJ11 on the left, using the top (coppertone) view.

Here's the latest layout. Can you reduce the size the way scalerobotics was doing? If I do it in Paint Shop Pro, it loses too much detail.

Below is the pinout from the data sheet with the drawing flipped over to give a top view and the outline of the RJ45 added.

Dave,
Does your data sheet show J8, pins 1-4 being VDD, VSS, RX, and TX (I may have the order off but those are the four pins used on the module I have)

Thanks Walter for scaling.

I'm using this datasheet. A tech at ConnectOne told me the pinout was the same on my pinless version.
