The wait is over

The new firmware was updated yesterday.

Thanks.

Now I'm patiently awaiting the documentation and newsletter.

Perhaps. The time between laboratory and release with documentation varies from a few days to a few years. The product manager told me they had it working about 10 days ago so nothing is really new. I'll go back to patiently waiting.

Their web site has said for the other long supported EMxxxx modules that the 5 interface lines are (in essence) programmable. I just need confirmation that this is also the case for EM500.

The module utilizes SPI interace and only requires five I/O line to control. Flexible mapping allows your application to use any five available I/O pins.

OK. I found the new firmware and documentation for the Tibbo. As soon as I'm satisfied with the details I'll get the prototype ethernet shield PCBs on order. They should be here within 2 weeks.

I can do the Tibbo testing. For ConnectOne, I have a nano LanReach but would have to solder headers to it to turn it into a nano SocketLan. I would rather not do that so I need volunteers to test all three ConnectOne modules. I'll give the volunteers an unpopulated PCB and maybe I'll install the SMT resistors and caps as I have those on hand. I cannot supply the rest.

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 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.
