Connect One Ethernet shield

Right click the JPG, View Image, then magnify. The GNDs are all just thermal pads that connect to the ground plane which covers both surfaces.

Hmmm,
Now I can see it...

I should have had you look at the others. I think the mini Socket iWiFi is upside down, backwards and, maybe, inside out. I'll try to straighten it out and double check the others tomorrow after getting a bit of rest. I've been putting in more time than is good for a geezer.

I think this fixes the problem with the mini Docket iWiFi being upside down, backwards and inside out. The Connect One drawings in the datasheet do not identify whether the views are top or bottom and some even complicate things further by showing topside components on what is a bottom view drawing.

I would appreciate it if those of you who are interested in these shields would download the Connect One datasheets and double-check my work. These all start to look alike after 2-3 days.


Here is the list of connections for the mini Socket iWiFi with my modified pinout drawing that presents a top view.


There is a mistake in the above drawing - pin 1 should be on the left. I caught it in the layout but forgot to fix the drawing.

I will try to get a chance to study them in the next day or so. Got a client with a problem... luckily it is not on one of my systems

I will try to get a chance to study them in the next day or so.

PM me with your email and I'll email the line drawings I made. You can check them against the datasheets and, if they jibe, check them against the layout .PNGs

I have offered the Gerbers to Connect One in exchange for their reviewing the layout. Stay tuned.

Why the offset square pads?

Why not place them at right angles, or make them round?

The one on the left above the I2C eeprom looks like a recipe for disaster (from a home-brewed PCB perspective).
